What Would Cause This?? My '02 WS6 A4 will sometimes surge while running 60-70 mph. I have an aftermarket mti clear lid, and it is cracked pretty bad where it connects to the tb. Could that be the issue, or is it possibly something fuel related? Any thoughts?

Check all 8 plugs, and scan for o2 codes. Mine was a dead sensor on bank 2, it surged at any speed though if I was cruising at light throttle. Very inconsistent so it was really annoying to figure out
