OK so I came on here awhile ago having a problem with the idle. I replaced the idle control motor and thought everything would be alright. Apparently I was wrong. My problem right now is that it keeps idling at 2,000 rpms and I can't for the life of me figure out why. The IAC motor is brand new, I took off the throttle and completely cleaned it till it was spotless, I even sprayed carb cleaner around the intake manifold while it was running to see if it would stutter showing if there was any leaks, no stuttering. Also when you turn on the AC the RPMS drop down to like 1,000. I give up, if any body has any ideas, I would greatly appriciate it. Oh also its throwing up the same CEL, error code message saying ideling incorrectly, like I need the CEL to notice. The only thing I have done to it is a cold air intake and catback exhaust. its a 97 GS. Thanks.

 

i had something like that happen to me a while back while i was cleaning my engine. it turned out that when i wiped the throttle cable it had slipped out of the metal sleeve that mounts to the bracket. when it came out it didnt go back in all the way when i let go after wiping it off. this put more tension on the cable , which made my rpms about 2500. this was just a freak accident but i guess a possibility.

 

you changed out the idle control motor but have you checked the throttle positioning screw? it's a small screw on the inside of the throttle body that used a flathead to screw in (to increase) or out (to decrease).

 

Hey I have I the same problem. So YOur car was shaking while on drive and they recomended you to replace Air control motor???

 

just for ****s and gigles try and spray some wd-40 on the spring that the throttle cable pulls and just rev it while spraying. See if that helps cuz i had that problem with my talon.

 

I tried the WD 40, no luck and I didn't see any screw or a place where one would go in the throttle body. And the cable was good.

 

oh and eugene, the car doesn't shake and its a manual.

 

what about a throttle position sensor.

 

There is that, thinking it might be that sensor?
Any way to test it, maybe by unpluging it or something?

 

that might work, see if the car runs differently with it unplugged.
