Odd idle sometimes

[wood_e]

Sometimes when I start my car cold it jumps to 2 grand then goes down to about 900rpm (which I consider normal idle). Sometimes when the car is warm and I start it the idle hops from 500-750 rpm, and sometimes if I rev it it stalls. I am getting NO codes from this. Anyone have any ideas? IAB valve possibly?

Thanks!

Could very well be a failing IAC valve. You might also just need to reset the idle speed program, for which you can find the instructions HERE. If resetting the idle speed doesn't work see if you can track down a known good IAC to swap out and see if the problem goes away.
