I just want to raise my idle, idles kinda low like around 500, want to bump it up to about 750. when its low like that, it the rpms jump a little and make a bumping noise from the car. when i turn the a/c on, it goes to about 700 or 750is and the noise goes away and smoother idle. anyone know how to do this without going to the dealer?
thanks,

 

Idle is controlled by an Idle control motor, it's electronic, no adjustment is available, sorry.

 

search for the cipher tool. It can do it. Cost $300 and can do alot of cool things and you can monitor a ton of crap on your car from your laptop. Other than that you have to go to the dealership

 

Yes, Cipher will do it, but it's $400 not $300.

I was talking to Mike @ Altered and he highly recommends this if you are at all interested in knowing more about what your EMS is doing. PLUS it allows you to bump the idle and +/- some timing I think.
