Checked my coilpacks and they seem to be fine, no cracks etc. My plugs are NGK iridiums which are only about 6000kms old. The air filters seems to be fine, its basically new, don't know about the fuel filter though. I haven't changed it since i bought the car 20,000kms ago but it was apparently changed before i purchased it. Gonna look at A/F ratio on monday. Could driving my car around temporary in this state potentially harm my engine? Also can ignition timing be cause of this problem? Does it have to be retarded or advanced when running more boost?
Thanks all
