My wife's '90 Ranger (2.9 V6 EFI) is barely ldling at +/- 400rpm. It has been steadily decreasing over the last year or so. It quit having a fast idle when starting cold. All I could find is that the Throttle Position Sensor may be bad. Has anyone run into this or had the TPS go bad?

IAC...

thanks, that is called the Air Bypass Valve on my Bronco, IAC on the Ranger. I'll check it out.
