Multiple cylinder Misfire
hi,
I have a 2004 Audi a4, the 3.0/v6 model. I had the cylinder misfire before, but it was just the random misfire, not a specific cylinder. I replaced all spark plugs, and ignition coils, as well as the CKP sensor before the code went away. That was about 3 months ago and just recently the codes are back, although this time it is: P0300, P0301,P0302, P0303, P0304, P0305, P0306. Not sure what is causing it this time, should i replace all spark plugs? idk, i also have the P0421, which is the catalytic converter O2 sensors being bad. so i dont know if the two are connected or not but any tips would be greatly apreciated.
thanks.
