Mine does it once in a while. After I tuned it up and replaced a few things like the TPS and IAC valve, it stopped doing it for the most part, but every so often on a warm start it still does it. I think it has something to do with the computer'* programming and the supercharger spinning up to speed to get enough air to the motor.

I wouldn't recommend replacing all of these parts - I sometimes still have the symptoms.

Sounds similar to what happened on my '93 SSEi a few years ago. On mine, it only idled low/stalled occasionally, and only when the engine was warm or hot. Giving it a little gas momentarily so it idled at 800 RPMS or so always got the engine running ok. I replaced the plugs and wires and then the problem became less frequent, but then I cleaned the throttle body and the problem hasn't happened since. By the way, even when it was idling low/stalling, the throttle never felt like it was sticking or binding.

Good luck.

Yeah, it is much more rare after I did those things and also cleaned the throttle body.
