when i start my car it revs high,drops down and revs back up to 2800 until it starts to warm up. when i first start to drive it it's real jumpy at 2k. very little throttle response and all of the sudden it kicks in which makes it very jerky and imbarassing to drive. after i drive for a few minutes, everything becomes normal. i was told it was due to the obd0-obd1 conversion i did. anyone have similar problems. my vac lines are right and iac is ok.

 

wats your setup? what fuel management are u using.
