I'm having some Issues on my 2000 Audi S4, and was wondering if any of you guys know anything about Audi/Volkswagon Igntion systems. So here is the deal, the engine is a 2.7 V6 Twin Turbo. I am having a misfire on cylinder #2. I changed the plugs. Still misfires. I switched the coilpacks with cylinder #1 and #2 to determine if the coilpack and/or wire was bad. Read the codes and still misfire on cylinder #2, so not the coilpack/wire. I than switched my ICMs (Ignition Control Module), each one controls each bank, Now I have a misfire on Cylinder #2 and #5, than I switched the ICMs back and just a misire on cylinder #2. So I am 90% sure that it is my ICMs, or at least one of them. Any Ideas?
