yes i did change the IAC with used one-10.5 ohms. the ambient temp does not seem to matter either way. i just drove it back to her house and it is odd when you take the car out of drive to park or neutral the rpms shoot up by at least 200 usually more than that. even at engine norm temp it idles about 900-1000. the temp senders aren't there two side by side one for ecm one for gauge?are there any others? i would want to test ecm one, right? sorry for all the questions, i work parts dept at a tractor dealership! local car dealers here don't want to tell you anything
