Hi,
I have a misfire and rough idle. I used VCP to look at the trouble codes and they are P0171, P0300, P0302, P000A and P2096. So far I have replaced the coils and spark plugs, and although the misfire isn't quite as bad it's still there. My next thoughts are fuel injector or maybe compression? Or perhaps there could be a vacuum leak, maybe the PCV?
Any help would be greatly appreciated. Anyone else suffered these DTCs and managed to fix it?
Thanks

Re: Misfire And Rough Idle
Hope it is not too late, or you already fixed it.
I would check the distribution belt, chain and chain pusher as it might be that the camshafts are misaligned, somehow. VCDS would be able to show you the camshaft angles - a pro mechanic would be able to tell if they are correct or not. The other way would be to check the fuel pressure, especially in the high pressure side, it seems that the mix is too lean..
IMHO..

Re: Misfire And Rough Idle
Thanks for the reply. I did manage to fix it, turned out to be a faulty injector on no 2 cylinder. Quite a labour intensive task! Hope the other injectors don't fail but so far so good [emoji1303]
