what did you do that ended up fixing the problem? I've combed the archives and found that this is a pretty common problem, especially for those who just got chipped. Some of the things I found to check:

- swap coilpacks, sparkplugs
- check MAF
- check ignition control module
- check all wirings/harnesses
- replace BPV
- check spark plug gap

So what'd you all do that fixed this? Thanks and Happy Easter!

Start with the CP's and plugs, then work your way to the IA (most likely the issue).

The part that connects the coilpack to the sparkplug. check that first by swapping it with a different cylinder (just the connector) and see if you get a misfire on the cylinder you swapped it with (bad connector) or if the misfire stays on the same cylinder (coilpack, ICM, sparkplug, etc)

ended up being the ICM.

I have a MY2000 A4...i don't think this affects me, right?

1) swap coilpacks, sparkplugs 2) check ignition control module
