It it normal for my 400 to run on slightly when shut off .Is it due to running only 87 octane.it was very hot today probably around 85 to 90 degrees. Should I up it to 89..think I am running around 12 degrees initial timing..or do I need 91..These cars are only around 8 to 1 max compression I think.The engine was rebuilt so not sure whats up..haven't really heard any pinging though just the run on for a few seconds.I also have edelbrock carb..didn't the q jet have some antidieseling solenoid or something..
80TA,pontiac 400,edelbrock carb,accel wires,dual exhaust,dynomax mufflers,no cats. CE subframe connectors. 99TAWS6 ..lots of mods.

Try a higher octane fuel.

Also can try 10 degrees and back that idle down some.

I daily drive my 78 T/A with 400. I use 87 octane camel piss and have no problems.
I agree with Bob's advice, except the fact that my car (virtually stock) likes a lot of initial advance and it's easy to have the idle set too high. Mine idles right around 500 RPMs in gear and I don't have any dieseling problems even in the warm Houston climate. ____________________________________ "Gee, what's that goat doing way up here in a cloud?" -Gary Larson TO THE MILITARY FORCES CURRENTLY ACTIVE, AND THOSE THAT HAVE SERVED; THANK YOU FOR YOUR SACRIFICE FOR FREEDOM.

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.
