Idle air control valve

Re: Idle air control valve
My Idle control valve didnt have any coolant lines hooked to it. I had coolant lines running through my throttle body though. Originally I just used a connector and looped those, it was good for a bit of power even. Hot TB isnt the greatest ting Now those lines feed the coolant on my turbo ;-)

Re: Idle air control valve
my buddy had the same problem, take off you intake and look in the throttle body there should be two holes in there. one of them leads to the IAC sensor plug that it'll stop the problem. well at least it did for us.

Re: Idle air control valve
I've been having high idle from 1500-2000 no vac leaks. the car stalls when I closed the Iacv hole the TB. I've tested 4 IACV. none fixed the probem. same IACV works on other people's cars. I've had this problem on 3 different engine and 3 different intake setup. I got tired of it and bought a edelbrock intake and TB still same problem, I changed ecus and Chips still same problem. I am sick of it. so now I just ignore it.
I was thinking about blockoff plate thing, but I would drill really small pin holes in the plate to get the car to idle. I plan on doing it this week

Re: Idle air control valve
Ive been having a similar problem. Car starts Idles at like 800. then falls to 3 the goes back to 8 for s while..It is rich as hell. my scanner is reading the front o2 sensor. and heater circuit..but he voltage isnt changing. so its rich like the sensor isnt working. changed sensor no luck. walked through a wirining diagram checked all the connection from the primary o2 sen. and followed them to the computer did a continuity check all work fine..just no voltage changed then i put in a gsr computer same thing.

Re: Idle air control valve
ive had this problem for like almost 2 years now. i just ignore it now and laugh when peeps think i wanna race them at every stoplight..... you would think theyd notice a looping idle, but o well.
Ive tried everything less than taking it to a shop and saying find the problems for me lol.
