Having probs with bad runing have just rechecked the codes and came up with
0303 or 0302
0300
0304
would this mean that this would mean a missfire on the same bank looking to change the plugs later today.
What do you think

P0302 Cylinder 2 Misfire Detected
P0303 Cylinder 3 Misfire Detected
Exactly what work did this guy do to your car recently?
-
Had rocker cover gasket changed on both sides and also oil cooler . When they did the job they used the put the same plugs back in which have done about 20k .
Just happen on the A46 last night on the way back from yours .Car feels like it going to cut out but does not also when pulling away feels like it is stutering then picks up. Starts fine 1st time but with a lower idle

1, 3 and 5 cylinders are drivers side bank 2. 4 and 6 are pass side. It helps to know exact code to identify which side of the engine to look at. Tbh i would be inclined to take the car to Mr Dtm if your anywhere near and hes not too busy. I for one would not trust your other mech who re used old plugs after Cam cover failure. They are only 8 quid each ,or something, from vx.

Thinking that after the leak plugs may be braking down :-/
-
first thing is new plugs, make sure they torqued them down too.

:o About 2 or 3 quid each from a stealer last time I bought IIRC.
I would check the plug wells haven't filled with oil again, that the rubber boots on the coil packs are clean and not still contaminated with oil and may as well change the plugs TBH, while you've got it apart.

Thanks All
Will get it done and let you know how things go.
Do the coil packs on the 2.6-3.2 go that much ?.
Think the plugs are best and not to much cost....fingers crossed :-/
-
i was worried about my coil pack, but whe i replaced the 30k+ old plugs, all was well again! ;D
I paid £20 i think for a box of 10 GM spark plugs.
-
See the post about that a few weeks ago. Glad it,s now ok... :y.hope min e is just the plugs. Could do with out having to pay for new coil packs.
-
:( :( :( Just done the plugs and still missing... looks like it will be the coil packs ...just of to get them :-/.
Would there be anyone around that could help me fit them this eve?.

Coil packs are a doddle to change, just couple of torx bolts, and leccy loom connector, then just lift out.
Be sure its the coil pack though, was there any oil in the plugs?
-
Something does not add up here.
Coil packs dont just both fail simultaneously (you have codes for both banks!)
Sounds like it could be an air leak or similar....
-
Hi Tunnie
No one oil dry .

Hi Tunnie

As MrDTM says, check for some air leaks, one coil pack failure is possible, but not both at the same time.
Do you have any other codes? - MAF sensor? :-/
-
will check and get back.
-
Where would be a good place to look for leaks can not see any so far
-
Main brake servo pipe.
Plenum to inlet manifold.
-
Just had a recheck and code is
0204
0300
0304
Would that point to one of the coil packs.
-
Obscure line of thought here..... ::)
If you've had the camcovers done then the inlet trumpets / fuel rail must have been removed? If so then I wonder if the loom connector is clicked together properly?

P0204 Cylinder 4 injector circuit high
P0204 Cylinder 4 injector circuit low
P0204 Cylinder 4 Injector Circuit Open
Now we're getting somewhere. Looks like it may be a problem with the injector circuit to that cylinder.
Try making sure the multi-way plug clipped to the lifting eye to the rear of the passenger side cylinder head is firmly connected (the larger of the two - smaller connector is crank sensor).
If that looks OK might be worth taking the plenum off and making sure the plug in the injector is OK. While you're there, measure the resistance of the injector - about 12 ohms is typical.

Have give it a check and all same ok pluged in well.
-
Steve...
You say you changed plugs - you would have had to take the coil packs out to do this ?
I don't think it's worth getting 2 coil packs as they won't fail together unless you're hugely unlucky...
I expect it's something simple..
-

Hmmm, I've been in the position where I got different codes, but with me it was my eyes getting crossed and out of focus as I'm an old git. I suggest you get to your nearest OOF member who has a TECH2 and able to provide a reliable report before spending lodsa dosh. TheBoy did me just fine, saved a bundle. Good luck :y :y :y
-
Is there anywhere else to look as said in the other post by Kevin looks like it could be injecters have check the multi way plug all ok . will look to take off the plenum do the injecters go or is it likly to be just the conection .... :-[ :-[.Running out of time as have to have it up and working by Friday.
Would anyone have any pics of the main parts to check.
Thanks
Steve

Will try to pop by on the way home from work tomorrow for 30 mins or so.

Ow yes, with the plenum removed, make sure al the connectors to the injectors are fully home (particularly number 4) as those not so familiar with the V6 often disconnect them when they dont know about the multiplug....and they take a lot of effort to fit back on!

Thats great thanks Mark :y your a star

Very good point !!!!

Just to check could an air leak from a seal give this and are there any around the injectors..
Thanks

An air leak could but, your last set of codes sudgest a faulty connection and hence my comment above :y
-
Steve mate, you really need to be exactly certain of the codes being flashed out. Make certain you have counted them correctly. Itook a video of mine on my mobile and played it back, pausing when ever i needed, to right down the numbers. Do this a couple of times, to make certain. It can be difficult as it flashes quite quickley, as you may have noticed, also i am thick and cant count anyway. Or maybe get someone to count with you, just to confirm the numbers. You may cost yourself a load of cash/agro for no reason otherwise. But i am sure Mark will sort you out if all else fails. Hope you get it sorted.

Hi Crris
Good point took me 8 times to count them as you say they very quivk and easy to miss count.
Check inj 2 and conection on it was loose. Put back and runing like a dream.
THANK for the help :y :y
