Hi there. I have read a few posts here about the same problem and just wondering if the icu could be the problem with idle at 1500 after the initial starting. Idle is fine until I hit the first set of lights..Checked for vacuum leaks etc and bought a second hand idle control valve but still the same.Heard about restting the icu also..How is this done

I'd check maf sensor, throttle position sensor, does your idle fluctuate?
