Dave, your current cylinder pressure test is higher than you old one even after a seafoam treatment.
Also, you need to find out how many degrees of vacuum advance produces. Take the car out with no vacuum advance and see if it detonates.

Your right Paul. Good eye, I must have done that when taking them out and bumped them. I always check that when putting plugs in. I set the gap at .040. I have new 43S plugs to go back in. I was thinking about getting those recommended NGK R5670-7 plugs. Not sure it would help. Dave |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
