Yes! When I first took out the Coil bank 2 plugs was under oil swimming. I cleaned them all up and put them back.
What can that cause?

That is due to the infamous cam cover gasket(s) leaking and the oil finding it's way into the plug wells, which in turn can cause the plugs and leads to overheat.

plug 2 is pass side bank so i guess you mean plug 3(the middle one) of the drivers side? Sorry just making sure.

I wouldnt think oil in the middle plug well would cause the whole driver bank to fail, but i guess the only way is to try/borrow i known good one first before changing the ecu...?

What did the coil pack look like when you removed it? Any cracks/broken bits of plastic with rusty metal showing through? Sorry if this is a repeat question.

[colin28]

No its no problem I thankyou for your help!
When I removed the 1st coil pack bank 1-3 was swimming in oil. after cleaning the pack and changing to another replacement there has ALWAYS been total cylinder misfire 0300 0301 0303 0305 every since the gearbox was changed.
I have changed the coils 4 times now.

I have checked and rechecked the leads. I have changed coil 4 times, swapped o2 leads, replaced camshaft sensor and spent 6-7 weeks now without a car.

Yet after all this and changing the camshaft sensor a few days ago after driving 1/2 mile the car starts misfiring again.

usual codes
0300 0301 0303 0305

I got a bad misfire of that type - knackered plugs

[feeutfo]

Well if it was me i think i mite have to admit its time to try another ecu, thing is there are far more experienced guys on here than me and they rarely see failed ecu's.

in conjunction with the other thread and the fact you've tried everything else....i would be onto the breakers i think.

try mutant cav and markey mark, breakers on here, for a start off.

where are you by the way?

[colin28]

Going to replace the plugs today and see if that will make any difference. of not then another Ecu is the only final option, I cannot afford to take to any garages because they charge stupid amounts of money I don't have.

[jonathanh]

.......and taking it to a garage is no guarantee they have any clue as to what's wrong.

I'm guessing a bit here because I don't have any experience of the newer coil pack system but I'm thinking like this:

1. are the coil packs actually firing at all?  Is it possible to do the old trick of inserting a spark plug, turning over and looking for a spark (as you would with a distributor/HT lead set up)

2. what does it take for a coil pack to fire?  Again a guess is, +12v, 0v ('earth') plus a signal from the ECU to fire.  If you could obtain a wiring diagram, I would then check that the coil packs are getting the basic power feed with a multimeter.  

If you know that the coil packs are getting the correct power feed and they are known good (even by swapping left and right bank THEN start to condem the ECU.

Looking at this from a distance I struggle to believe that it is an ECU failure coincident with the gearbox re-fit.

where 'bouts are you, if you're not too far aware I'm happy to lend a fresh pair of eyes

[colin28]

Changing the plugs has now seemed to sort out the misfire.
But there is still fault code 0130
P0130 O2 Sensor Circuit High Voltage (Bank 1 Sensor 1)
P0130 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
P0130 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)
P0130 O2 sensor circuit malfunction (Bank 1 Sensor 1)

What can cause this and what can I do to solve it? Nearly there.

Thanks to everyone for there help so far. Just 1 more fault left

broken wire?  that could have happened with the box change.

[RobG]

Check the wiring from the sensor nearest to the manifold end for fraying etc.

[jonathanh]

or try swapping the plugs on the side of the gearbox again + reset codes.  as per Mark's early posts

[over50now]

When I was doing my cam covers, checked out the how to guide and other posts.  Several others on here mentioned that they had a spare pipe that seemed to originate from low down in the bulkhead, and wanted to know where it went to.

Replys were to te effect:- if got manual don't worry about it.
If Auto it's something to do with Auto box.  If you've had a new auto box fitted, did the garage forget to reconnect this pipe.

I'm totally guessing here and probably barking mad

What do you others think, is it viable?

I have changed the leads back and reset the codes.

Drove around the block and the code 0130 came back.

What else can that be?

there is something that is causing a problem with the lambda sensors.  next move would be to check out the wiring to these sensors - beyond my expertise I'm afraid but I would start at the plug end of things and work back up - this should pinpoint of there is a problem in the loom /wiring somewhere
