Run On
[QUOTE=hal101;5842376
but when i turned it off it ran on for about 3 or 4 sec is that a sign of detonation that i cant hear or nothing to worried about?[/QUOTE] If there is run on without spark (ignition turned off), I would call that detonation. (Just enough to keep the engine turning, maybe without hammering the bearings) As Paul stated, if it was pre-ignition, the engine would cease to run. When I had it I worried about it as the engine was more like bucking than running at 1-300 rpm. I don't know what the minimum rpm an oil pump requires to pump oil, but that was my concern. Did not have the presence of mind to look at oil pressure.

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.
