Idle and low rev accel problem

petemun, Jun 2, 7:49pm
I just bought this car very CHEAP with this issue so I dont know the history of the problem coming on.

97' pulsar autech sr20de. Most of the time it doesn't idle properly so I'm thinking it could be the idle air control valve needs a clean out !
Im also wondering about the throttle position sensor as when you go to accelerate from low rpm (below 3k) sometimes it will stutter so if you give some more gas it will go ok or if you take foot off the gas and try again it will sometimes be ok. The car is fine at highways revs.

The iacv valve is a pita to get to so I thought id ask advice before I start. What would you check / do first ! check tps voltage ! or could it still be just he iacv !

Any one had experience with this problem !
