When at TDC is the reference sensor screw supposed to align up with the sensor? Someone was complaining a while back that the fidanza flywheel reference mark was off by an inch compared to the stock flywheel. I think I may have the same issue. When at TDC the reference sensor mark on the flywheel is about 4 teeth off from the cam TDC mark. This would explain my idle issues.
Can someone please confirm..
