Default StreetTuner/Cams/Idle

Just wanted to share a solution with anyone having idle issues caused by larger than stock cams, a drive by cable throttle, and tuning with Street Tuner/AP.

I must give credit to mick_the_ginge for offering this solution to utec users -- See Here.

I put together a hybrid 2.5/2.0 with aftermarket cams, and ever since have had idle problems -- not only lopey, but the car would stall almost every time coming to a stop.

The solution -- use the idle set screw on the throttle body to open the butterfly up a little so the engine gets a little more air flow at idle (cams need this). This will also cause the throttle position sensor to tell the ECU you have more than 0% throttle at idle -- use Street Tuner or your AP to reset the ECU -- this will zero out the throttle position sensor at the new idle set screw position and allow the car to idle correctly.

I adjusted and reset in small increments until I was happy with the idle and idle recovery. After three rounds of adjustments, the car idles very well (still a little lope, but not as bad), and more importantly, the engine does not stall when coming to a stop anymore -- doesn't even dip below the set idle speed (I have mine set at 1,000rpm).

This is awesome -- those of you who have a car that stalls at every stoplight knows what I'm talking about.

Thanks Mick!
