I think I may have messed up something...

last week I was cleaning my motor and removed the throttle body. I removed all the sensors and and cleaned it with b-12. I cleaned out all the carbon build-up thinking I was doing a good thing.

After aI put it all back together, when I crank the car it reves up to about 2k then slowly back down to 1k and idles there. I figured I may have damaged the IAC. So I ordered one from Jason and installed it. Still the same thing. Since then I have replaced the throttle body gaskets and checked all the vacum lines. I cant seem to find anything wrong.

Has anyone esxperienced this before or know of something I maybe can check??


thanks

 

is the 1k idle in park? because thats where mine idles

 

it actually idles about 1100 - 1200 rpms. It is to high. before I cleaned the throttle body it use to idle at about 800 rps or so. Now when I am sitting at a light of stopping at one i have to use a likke more brake than normal. like she is wanting to take off.

 

Is there any way to check the IAC, maybe I got a bad one, or is thre something after I install a new one to reset the comuter?

 

try resetting your IAC...

hold the gas pedal cracked open (not too far) and start the car and let it run for 5 seconds. turn it off for 10 seconds and then start it back up again.

 

Ok will try that tomorrow,

any other things I may check out? What about removing the IAC. Plugging it up and turning on the igntion to see it if moves out of in? can I test it like that?

 

I did the same thing in cleaning the TB and mine is doing the same thing. Sometimes it does it and sometimes it doesnt. I dont get it.

 

well surely there must be a something causing this, and a solution for it. I have spoken to serveral people who have run across this same problem.
