We had an engine that was under performing and it turned out the stock heat range spark plugs were too hot. A worst case once a newly built engine would only idle until we changed to a colder plug. It can be a night and day difference. Just offering things to try.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world.

Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
