Re: 1993 S4 need help
cat is still on...when in neutral it idles fine. but when you turn the wheel either way it revs up a little.
i changed the fuel filter. found out that egnition coil #4 has no spark, replaced it, still no spark.
so it runs on 4 cyllinders thats why when in low RPM its choking. what could be tha problem...
