thanks for the help team. New plugs about 6 months ago. getting repeated codes for cylinder 4 and 5. Replaced coil packs last week. Worked for about 5 days, back again. cleared the code, made sure the packs were in tight ran it. Seems better but still jerking around 40-50mph. I'm thinking it could be the harness or thev connector (clips arent looking the best; maybe a poor connection). What ideas do you have? i dont have a vag, just a regular code reader.
