2003 gti 20 ae, like the person in aug, i had stumble when accelerating. intermittent but continued all the way home. read codes now how best to proceed. codes po300 and po304 -multiple and cyl 4 misfire. so what pathway do i follow to track down the source of the misfire? is it related to detonation? dealer only items? i bought the car from the dealeer with 1100 miles on it and first time a mechanical problem (except for the windows falling out of the tracks and a seatbelt switch which is recurring) does the online book you promote have the answers in a simple format? thanks rob.
