I have a lunch scanner. It's one u can make keys an stuff with . I think it will graph all that. My problem is i can drive an drive an it may not do it . So the chance of me being able to actually have the scanner set up an it misfire are slim. So if the reluctor has move it will cause the same issue? I'll pull the cover an check. I found new gm cams both under 200 . Also u said gas pedal sensor? How could a person test that ? I have done about everything possible I can think of. All the timing is ac Delco. Anything I have replaced is. I can rob parts off a parts car that jumped time.
