Jumping idel

[formula driver]

I need help with this quickly guys. My car starts up fine but the idel will jump from 1800-2200 rpm. Its a very steady bouncing, it causes the MPG to jump as well. My ICV is good. Please give me some ideas of stuff I can check.

Vaccum leaks are a major casue of jumpy idle. Check all your rubber under the hood and connections at the throttle body.

Will do. Thanks

Any other suggetions guys?

Switched the throttle body out for another one I had and checked all my vacumm lines. Is there no one on this forum that can atleast tell me what to check?????? What are things that could cause a jumping idel?

Just looking at the lines doesnt mean that you actually checked them for a vacuum leak btw. Get a vacuum gauge for cheap from Autozone or something and see how much vacuum the car has at idle. It should be around 17-20Hg or so.

Will youve been one of only few to help me out. Thanks

I think its either the ECU or the harness that runs to the ICV. Im burnt out but Ill check a few more things later.
