Title: Code 0300
Post by: alunonhisown on 02 March 2010, 10:59:32
Am I to purchase a new Coil Pack ?
As I have the above code will a new 2-4-6- Coil Pack cure my problem?
Should I get both sides or just the one, as there is a history with this car on cylinder 4.
This was taken from SARANBAILEYS original Advert for the car.....
.....I have had the car Tech 2 on missfire as there was condensation (the cold weather caused this) in plug number 4 causing it the problem, now cured. Engine management light off Cats both working fine.
So, are we agreed that it is pointing to the 2-4-6 bank of Coil Pack?
I really need this sorted as my CRB will be back this week and I need the car for work.
If this cannot be resolved I am going to have to bite the bulllet and get shot of it, for obvious reasons I need reliable transport for work.
All help greatly appreciated

if you have a miss fire yes, if not no.

Are you aware of any engine issues while driving?

May well be an old code from previous. As you can see from the video in the paper clip test thread, my car had 0300 and 2 other missfire codes when i got it. It has been fine in my possesion.

Try not to panic Panic Pants.  ;) ;D

Code 0300 means ' random/multiple misfire'. You can see what the codes mean if you go to 'maintenance guides', then 'index', then 'engine management codes', then 'Y26SE and Y32SE codes'.

This code points to a random misfire rather than a specific cylinder, and when you bought the car, they stated that the fault on cylinder 4 had been seen to and cured. I'm sure James would have seen a problem when he changed your spark plugs if there had been one.

I wouldn't go buying bits and pieces on the off-chance that it may cure the problem. As I said before, this is not a big deal at the moment and the car isn't going to let you down. You drove it to France and back in a far worse state than it's in at the moment. You may need a new coil pack, but there's no point wasting your money yet. Hang tight to see if someone is able to give you a proper diagnosis.

Yep. Proper diagnosis being the key.

0300 means random misfire. In other words, the ECU is unable to determine which cylinder is missing. A faulty coil pack will always misfire on the same cylinder(s) so I think we can discount that straight away. £80 saved. :y

IIRC, the car had issues with a totally clogged air filter amongst other things which could well have caused a misfire. Were the codes reset at that time?

Do you know for sure that this code appeared since everything has been sorted out?

Does the car misfire or show any symptoms when driving?

Is the EML actually on or is the code just stored?

If the answer to the above is "no" you have nothing to worry about. Next time you're passing one of us with a Tech 2 get the codes read and cleared so you know that you are not dealing with historical information. :y

The codes cleared a few hours after James did the service. Then next day the Orange EML came on.

Do you know for sure that this code appeared since everything has been sorted out? YES, Definitley

Does the car misfire or show any symptoms when driving?
No None at all. Just stinks of fuel when starting.

Is the EML actually on or is the code just stored?
Yes, ON at ALL times.
Hope this helps.

You need to recheck the codes now. It could be IIRC 0420 and 0430 which is a common 3.2 problem and sorted by moving the lambda sensors.

Is this just from cold .. or every start ???

As a thought .. start it up, run until warm - I expect EML to be on if it had a problem starting ....  switch off and leave for 5 minutes.

Restart ... what happens ??  ie .. does it start well ?? is the EML light on ???

Trying to see if it is a cold start problem . or an "every start" problem .. if its the latter it might be the start of a crank sensor failure ????   you don't always get an indication of these until they give up completely

Isn't that the codes that Entwood posted? If 0300 is showing, that's putting the EML on, so the car has a 'general misfire' ...............

Post by: Entwood on 02 March 2010, 17:27:17
0300 = general misfire.

So its a misfire that the ECU can't pin down to any particular cylinder, or it is not consistently the same cylinder. ... if I understand the system at all ... (probably not)  .. :(

Worth checking that all electrical connections are firm, that the low tension wires to the coilpacks are undamaged and dry, and no water/moisture has got into either coilpack.

It might be unrelated to the ignition side of course, as a "fire" needs both ignition AND fuel... but what could cause a "random" type failure of fuel to igniters ??? or "random" igniter operation ??.

Possibly a crank sensor not telling the ECU the correct rotational position for when to fire ???

Just random thoughts .. nowt else ..  :(

On SWMBO's Astra I changed plugs, which fixed a 0302 for a few days. Then 0300 seemed to have been 'cured' with a bottle of Redex  :-?  :-?  :-?  :-?

Yes, could be, rain was getting in through the scuttle on mine, causing a misfire by dripping onto the coilpack. Had to seal it with bathroom sealant

DI, can you get the car into a garage overnight ???  Might be worth getting into the dry, leaving the bonnet up, blowing some warm air around with a fan heater and trying to ensure all wiring has dried out .. if the problem goes away you might have found the cause without a lot of effort .. :)

£4.50 - that's a bloody bargain for a nearly 40-mile journey missus! (The conductors' bonus is factored-in to this too).

Basically, tell 'em that the EML is lit, and you want it diagnosed.
Say nothing about any work that's been done - only that you've just bought the car, and need it sorting ASAP.
You need to know what's at fault BEFORE committing any cash to it.
Take it from there ........

IMHO, you'd be crazy to put it into a dealer - or ditch the car on Ebay when you have offers of help on here.

In addition, if the car is running smoothly, there is no misfire. There might have been a misfire detected at one instance but, unless it has an obvious, constant misfire it will do no harm to use it until you can get to someone who can diagnose it properly IMHO.

..and you're more likely to find one of those here than at a main dealer, again IMHO.

A main dealer will plug into a tech2 and tell you it has a random misfire (you already know that) code 0300.

They will then change components on a haphazard basis until the light goes out .. or they will change a component and erase the codes to PUT the light out.

You will then pay a large bill and drive away. If they have not actually changed the right bit the light will come on again in about 20 miles.

You are then back where you started but with an empty purse .....  :(


The only way a tech2 sesion can help you is if the person using it

a) knows what they are doing
b) spends the time to do a PROPER live data analysis

You may then have a slightly better chance of having the problem correctly diagnosed.

You're obviously a woman, and need this done yesterday  ;D so go ahead and take it to Southern and see what they say. However, get your purse ready and don't hold your breath waiting for them to actually do anything about it without spending LOTS of money.

If it was me, I'd just drive it as it is for a while, irritating though that may be, and drive it to TB or Kevin Wood when it is convenient for you both. But I'm not a woman  :P

Fine Mr Cool,
But Again, I am taking the advice of James who advised against using the car whilst the EML is on with possible Multi Misfires.
As for yesterday, I am happy to drive it, but I am starting a new job in Pontypridd quite soon, and I need a reliable car to get me there and back.

It was a 4 pot Astra, as said I put a load of Redex through, but I beleive those engines do have their own problems.

I have never even heard of Redex.
Some oil treatment as a guess.
But I have no clue.
I will go and Google it.

Di .. the point we are TRYING to make is that an 0300 is a bit of an odd code ... if you had a coil pack failure, or a single coil in the pack .. you would get specific codes for those cylinders ... 0301, 0303, 0305 for example.

Your error is non-specific .. or for want of a better word .. random ... which is why no-one can say .. "change this"...

Hence my suggestion of drying it out as moisture can cause odd things to occur.

A "proper" live data analysis MIGHT, just MIGHT indicate where the problem is by looking at the data and checking for anomolies.

I suppose you could chop a plug off & try it!

I was merely pointing out that I bought a coil pack to fix an 0300 code because symptoms seemed to suggest the coil pack might be fubar'd, but the coil pack is now sat in my garage after being on  the car for a few miles. It wasn't the coil pack at fault.  :y

Diane,

You told me, that the car was "shaking" and running like a bag of nails and stank of unburnt fuel.

It was on this basis I advised against driving it, due to the fact that this sounded like a misfire symptom and I didn't want you to damage your cats.

Well, this is new information, and it changes things.  :-?

For info, the emissions light on a DBW car will flash if the cats are believed to be in danger. Doesn't sound like it's in a state where it can be driven far.

Also see The Boys Tech 2 sight, link at the bottom of one of his posts.

There are numerous causes of a random miss fire, trouble is non are showing a fault code to go with the 0300. Live data shows figures and outputs from engine sensors as the engine runs.

A for instance for you, my car has issues on hot days when starting, just cranks on the starter but wont fire, doesnt happen often for obvious reasons, so its nothing to worry about, but one theory was to check the air temp sensor built into the maf, this is used during the start up procedure as a referance before the maf (Mass Air Flow) sensor kicks in, or something like, the details are not important, but tech 2 shows this info real time.

My car didnt show ANY issues at all under live data, yet the symptoms pursist albeit very rarely. Its not necessary to hit the panic button at every issue or code that appears to point at trouble. If we did that nobody would ever buy a car at all. The Boy has a little mission when ever he tech 2's a car, he can always find "some" issue or other, and usually does. The cars history can almost be read to some extent, in fact his own car throws a gear box code of some sort and is concidered normal i believe. BMW e39 diesels throw a fuel pump code to do with fuel pressure as a matter of course, they run perfectly and you would never know the issue was there.

So i think its wise to take note of the issue as you have, and get it checked at a convenient time to you and your nearest admin with tech2, i guess that would be The Boy? And make the journey with an open mind ready to accept the fact that there may or may not be anything wrong at all. Chiiiiiil Winstaarn.

I suspect some owners would be delighted to only have that code after the pedal trick.


Edit, unless of course new info comes to light, i was writing this as James posted.

Given the latest bit of info ... "shaking and stinking of fuel"  which is a tad different to the original "smells of fuel on startup" ... ....

may I ask the following ....

Does the smell of fuel come from the exhaust or under the bonnet  ??

Exhaust : unburned fuel, misfire probably caused by ignition problem, risk of damage to cats by petrol.

Underbonnet : Spilt fuel, leaking pipes/injectors, misfire probably caused by insufficient/incorrect fuel in cylinders. Serious risk of fire

Now, as I was the one who suggested a drive to a tech2 based on the original information I now suggest the opposite. do NOT drive the car until you KNOW where the problem lies.

It is difficult to long range diagnose at the best of times .. but when the information given is incomplete, or changes half way through, it becomes impossible.

If you want us to help ... at least give us the information we need in order to help !!

Wishful thinking and guesswork never fixes anything.

Right, a good nights sleep and a cup of freshly ground coffee and I am right for whatever this car and the world can throw at me.
I believe that the smell is coming from the exhaust and not engine compartment.
The EML does not flash, it stays on constant.
The car only 'shakes' when I put my foot down on the drive and rev the car to say 5-6000 revs, I was trying to see if the EML would go out, silly me I know, but was trying anything, not knowing anything, so, there you go.
I will start the car now, it has been stood for a good 18 hours since I started it and report back about the fuel smell.

I would have both coil packs replaced,the car has done over 100k miles,the coil packs appear to have been contaminated with moisture and oil at various times.If they are the originals then maybe time has taken its toll,if they have been replaced at any time then are they genuine.Either way contamination by water or oil in plug wells and that seems to be recent can cause(lets call it strain) to internal circuitry.If that doesnt provide a cure then put the old ones back in and sell the new ones that way keeping the costs of this method of attempted cure down.

Easy to eliminate earthing problems with a jump-lead.
Securely clip one end to, say a manifold stud/nut, then clamp the other end to the battery negative post.

I have splashed out on something I personally need.

A peice of kit that can read, reset fault codes, and display a range of real-time live data on any ODBII enabled cars. (Needed it for the peugeot!)

Not quite the real-deal such as tech2, but nonetheless would give a very good indication of feedback from various sensors and components, as it does live data.

Happy to hook it up and get some readings , it would not cost anything and will provide clarification on the way forwards

Just need to sort out a convenient time

Sorry, just seen this thread - I'm sure people can appreciate my mind is on other things than OOF, seeing as my own car is 90 miles away, and in a bit of a mess currently.  In all honesty, I'm now tied up until April.

Not sure how Kevin Wood is fixed either, seeing as he has had a prang in his beloved car, and needs to spend time stripping the car down to get the chassis off to Westfield for repair.

I really hope we are not expected to drop everything to help others when we clearly have major car issues of our own.



So, forget the codes for a minute, lets talk about symptoms.

Idle (cold)?
Idle (hot)?
General driving?


If the car appears to be running OK, but throwing a P0300 (but no other P030x codes), worth double checking the engine earths.


Once you have done that, consider taking offer from local member to do a code check and a live data read.

I have a 3.2 auto, and having dome cambelt and covers with a service (new GM plugs etc) at 68000 miles I noted that one of the coil packs had rusty deposits on a spark plug 'boot'. As I didn't have a replacement to hand the original coil packs were used. Within a day of doing the work  it developed multiple misfires etc. Got the codes out using the pedal trick and got the 0300 codes and others relating to misfire were present. When it happened, I was driving at low speed and the EML flashed for about 10 secs and then stayed on.
I replaced the coil packs  on both sides and normal service was resumed....
There was no oil in the plug wells, and it would appear that prior to me purchasing the car in 2007 the engine had been steam cleaned/jet washed (very clean and dressed up with a back to black spray). The water had obviously caused the premature failing of the coil pack.
I am in no way advocating the replacement of parts without correct and complete diagnosis, however it would appear that the symptons you have described are identical to mine. Unfortunately miggys are now older vehicles and are starting to show their age, by parts failing, that will require replacement.
On old car with distributors and contact breakers, ignition components (points, rotor arm and distributor caps) were service items to be replaced at regular service intervals, sometimes yearly.
The coil packs on the 3.2 replaced these ignition components and do not require replacement at service intervals. However they do fail and will need replacing at some point in the vehicles life especially if it has completed a significant mileage which I would suggest in excess of 100000 miles is. Remember as well it is a second hand vehicle and although you may have a service history you do not know how it has been maintained (service records can be ficticious) and you must expect components to fail and the associated worry that goes with that ;) ;)
Good luck
