Hello all. First off Im a Diesel Tech but I just got a 2009 Ford Explorer that has a high Idle and throws a code. If you clear the code it idles just fine for a few days. So we threw a few parts at it. New throttle body, IAC, TPS and a new MAF. Still the same problem. While veiwing data stream everything seems normal for running at 2800RPM... If anyone has any ideas it would be much appreciated!
 






Basically youve eliminated the three suspect altogether by replacing them but have you reset the pcm and let it relearn the idle? What are the code especifically? TPS and IAC? On a 2009 you basically have an electronic throttle body which include the IAC.
