Problem with ISC Duty Cycle
I am logging my isc duty cycle and I can't get it to change at all. No matter if I adjust settings in my tune or close the throttle body stop screw, my isc duty cycle is always 14.91. Makes me think my PCM is not working right but everything else is fine.
Anyone have any thoughts on this? I'm stumped.
Oh, I did back probe my IAC and started the motor and I saw the voltage slowly go from about 8 to 12. So it seems the PCM is doing something.
