Rough start Options

[Followtheornghat]

I have been having a problem recently were when i go out to start my car it turns over then stumbles down and stalls out. If i give it gas its fine and holds there and then catches itself and sits at a normal idle, but only after its been held at 1k rpm for about 20secs, I had a cel but it was code 71 for the egr valve (had a crack in the vacuum line but fixed it when i replaced my brake pads this weekend) No cel anymore but the car still hesitates sometimes when the car starts. it cranks over and revs up to about 1k, then just stumbles down till it dies, (about 2 secs after starting) Im wondering if this could mean my TPS (throttle position sensor)is going out or if its something else. Because my TPS isn't throwing a cel code.

I had this problem before, and my mechanic gave the IAC a thorough cleaning as well as the throttle body and it was gone.

i recently cleaned my throttlebody out but didnt mess with the iac cause i know it works in sync with the tps and thats controlled by your computer so should i just do little adjustments until it clears up?
