  • I changed plugs and wires but.........

    about 2 weeks ago i started getting misfires on cylanders #3 and 6 at low rpms (around 2000), i went in and had the plugs and wires replaced by the dealer. As i was leaving the dealership i floored it, no misfires in the low range, but now im getting misfires left and right in the upper rpms!!!! what else could be causing this? coils maybe?
    I guess I\'d have answer your question with another question.<br /><br />How many Abidiginals do you see in modeling??????<br /><br />headers, 3inch magnaflow cat, Loudmouth<br />99 Midnight Blue Firebird<br />3.8L A4

    Usually if it is misfiring on 2 cylinders it is a coil pack. I said usually that is the cause, not always though. In this case it is. It is the first coil pack you see in the line of 3 that is bad. The 1st one controls cyl 6 and 3. What do ya know? Anyway good luck, i'm having some problems myself with coils.

      It is possible that those misfiring plugs are not gapped right, that is what was wrong with mine...spent many hours under my car...
