a bit of background first, its a audi v6 we had in for service last week about 130k miles on it.

after the service it drove out fine. Anyway a couple of days ago it was recovered as it stalled on the owner. Upon arrival to where it stopped the car started and drove back with a small misfire at idle and low revs but heaps of power at high revs.

We got it back to the workshop and fitted some new plugs, then leads then i traced it down to no 1 & 5 cylinders. Checked and double checked firing order etc.

Fitted new coil pack and its still no different.

The reason i changed plugs and leads was because the leads were old and plugs had done 10k since last change but coils was then changed after realising you can remove no1 and 5 leads without affecting the engine.

These 2 plugs are soaking wet with fuel when removed asift they are not firing but the system fitted has 3 coils giving the spark to 2 cylinders at a time but the misfiring cylinders are both from different coils??

Im starting to think about injector issues, Are they staying open?? If so why? If not, why are the plugs so wet?? Think i will check the injectors with the low amps clamp monday.

Any ideas welcome!

Thanks in advance Brad
P.S it has codes relating to 02 b1 s1 and b2 s1 low activity as expected with a rich engine condition. src=http://cdn.boardhost.com/emoticons/grin.gif>
