ok so i have changed out the FITV and the IACV. and i am still getting a jumping idle. i have done everything i can think of possible. and still i am having a rough idle. i changed the FITV and it got a lil better. and then i Changed the IACV idle got a lil better. but still jumps from idle to about 1600 to 1700 rpm's. i sprayed carb cleaner around every line on my IM and nothing is working. Tired messing with the idle screw still nothing. does anyone have any idea what the hell is going on?? im so tired of messing with my car and it not running right. so can anyone please help me.

 

have you read in the faq on this? make sure your throttle cable is not too tight, thus pulling your butterfly slightly open at idle. i have seen that before.

 

yeah the butterfly valve is closed. it has been running fine for the past two years and then all of sudden it just started at a stop light.

 

Check your vacuum ports, an open port can cause some crazy idles.

 

see if the fitv backed out too much

 

Almost every time my idle has gotten jumpy, its been because the FITV was messing up. Maybe the stock adjustment on the new one was off. I take mine and tighten them all the way up.

 

when mine is tightened all the way I idle too low, I backed mine out but i did it too much so it idle'd around 1200 sometimes. I'd do all the way down then 1/4-1/2 turn back out
