Hello, I have a 2000 a8 d2. I have a misfire that is stumping me. I have the p0300 and p0308 code which I believe the p0300 goes with the p0308. I have cleaned and verified flow on the injectors. I have switched around both the spark and ignition coils but it still misfires in cylinder 8. I believe the ignition control module is now integrated into the ecu so I cant just easily change that. Any ideas what I can check or replace next to try to fix this? Also it is a high rpm only misfire. It happens around 4k rpm under load every time but doesn't feel like there is any loss of power. When it happens the mil flashes for a bit then goes off.
