Hey guys I just got back from the track, and after my second run at the track my idle is all screwed up. It idles realy low, and you can really feel the vibration when standing on a stop light. I have a turbocharged 93 PGT. So these are the things I'm suspecting

vacume leak
fouled plugs - I'm running 4 heat range colder plugs
and posibly timing... my timing was really lose so I think it might have skipped a tooth or something.
Anyways I will check these things tomorrow. Anything else you guys think I should look for?

A quick assessment of the engine internals is in order: pull the plugs out and examine the insulators and electrodes, then do a compression check. If these check out, start looking for a hose that popped off due to boost pressure or a loose clamp.

What makes you think the timing (belt) was loose before the run? (And, out of curiosity, if you knew it was loose why were you drag racing the with the engine in that condition?)
