When I start the motor cold it starts up just fine, idles at around 1000, when its all warmed up it idles at around 6-700. But if I try to start it up right after a drive (at operating temp) it will sputter, try to stay alive, then bog out. But if I give it a little gas to help keep it alive for a few seconds then she will idle just fine at around 6-700 without dieing. Drives fine.

I thought this was a vacuum leak, but I couldn't find any leaks and its odd that it only happens when the motor is warm or hot. HELP!!

I have a stock sr20det with front mount, exhaust, and recirculated BOV. Pretty confused..
