I've got this problem with my 93 ZJ 5.2L

Every now and then when I start it, the idle will get kind of wonky, but it's not really the idle as much as it seems that it's not running on all cylinders and will have this miss, as you press the gas the rpms go up okay, but you can feel that there is a miss and not firing all cylinders. After about 10 to 30 seconds it's fine again.

It basically does this on oddball days for me. Meaning that if I start it in the AM and drive to work, then 4 hours later I start it and return home it hasnt had this problem.

But if I drive to work in the am, leave in 2 hours, stop at the market, then when I restart from the market it *might* do this, it did it today.

I seem to remember seeing a TSB somewhere that talked about hot starts and stumbling idles, so Im trying to find that one again to see what it's instructions are.

Thanks,
