idle issue 2000 4.2
Hi guys I got this truck cheap because the guy couldnt figure it out its a 2000 4.2 l f150, when i start it cold it idles just right i can rev it and it comes back to 900 rpm but once the temp. reaches the c on the temp. gauge things go bad when I rev it the idle goes up to 2 grand and usually stays or moves up and down, Its got a new iac and tps, if I disconnect the iac the idle comes down to 1000 and seems fine , no codes are present, Im wondering since it only starts to do it after its warmed up that it could be the engine coolant temp. sensor any other ideas thanks,
