I've had that happen to me,That code would pop up,Go away etc and What's worked for me is clocking the OPDA like if I was advancing/retarding it little by little(little 1/16th increments or so)Code went away and I was fully able to rev my jeepI got a cam and crank correlation code the other day. I had to use a scan tool to set the cam and crank difference as close to zero as possible. I also hooked up my scope to see how the sensors align at zero difference. This was the scope data. Looks to me like the last crank tooth before the gap falls right in the center of the first cam tooth. Set like that mine was reading 0 difference, and the code went away. I thought it was interesting.
