2002 Audi A4 3.0L Misfire, MIL Lamp on
I have an intermittent misfire on #4. I swapped coils and plugs, miss still on #4. I have spark and noid light. It seems like it has to sit for 20-30 minutes before it acts up and only lasts for 30-45 seconds. I also hear slight valve noise. I am thinking lift...
