Will atap show bent pushrod or floated valve?
After autotapping my car due to its lack of performance lately, I lost 2mph at the track thought I had a bent pushrod or a floated valve. I made about 10 runs, my o2's were between .90-.89 for the first two with no knock retard. Then the next three runs o2's dropped to .87-.88 but still no knock retard with 25 degrees of timing. Will atap show a bent pushrod or anything of that nature ie: knock retard?
