Anyone with a 96-01 mustang cobra that can tell me what your idle throttle percentage is. I'm diagnosing an issue with my car and someone jacked with the screw on the throttle body so the pcm is reading it as 20% and my car will not activate the iac valve at that %. Anyone know what percent yours is at? Think it was around 13.5% factory but want to be sure.

 

Check the voltage from the tps sensor it should between .9 and .97 with the throttle closed

 

I'll check. I also noticed my full throttle percentage is 92%
