One week of driving and no code. I am hoping it was the PMD. The PMD I put in was the one I used for years with the old pump. After I replaced the pump in December I used the PMD that came with the rebuilt pump. The engine seems to run quieter and smoother. Crossing fingers

CPS replaced in December by shop as they could not get it timed after I replaced the pump until they changed it out. I will replace OPS if i get code again, thanks.
