'97 GC hesitation...

my '97 GC frequently has a brief hesitation after restarting a warm engine. (I6.) When cold, I never notice a hesitation at all. I can drive until it reaches operating temp. If I restart the engine before it completely cools down, it will hesitate some on the first acceleration. It will occasionally have a very mild backfire or 'pop' sound, then accelerate normally and run fine the rest of the drive. This has never happened when cold. It starts fine (within a couple turns of the engine..) Any ideas?

thanks, cal

Or coil. When my coil was going I got the same hesitation till it just simply wouldn't start. (too bad they won't let folks just hit the coil with a blast of freon to cool it off) :) That was an easy check.

I didn't mention that it only hesitates once after restarting. I can drive hundreds of miles, stop and go, and it never does it again....until I shut it off, walk away for a little while, and then restart before it completely cools off. Does that make any difference concerning your ideas? thanks for the help so far!

I built a "leak detector" out of a 110VAC Neon lamp from radioshack and a length of insulated wire. Just run one leg of the lamp to the chassis ground and the other down a dowell. If the lamp flickers you found a leak.

Fairly simple and cheap.
