ETC fault


Recommended Posts

Posted elsewhere but figured here would be helpful too.

How's this for some farkery? The car was trying to rev at idle and drive itself in gear and while I could get it mostly sorted by some quick changes to the idle airflow, there was no reason for those changes to be needed. First thought was an intake leak but I know there wasn't one, so where else could it be getting air from? I measured the throttle body values in Forscan with another throttle body I have, and the one on the car was open half a degree more at idle. Not much ay, but I adjusted it back down to 7.5 degrees from 7.94 degrees and it fixed it. Lol less than half a degree is enough to send your throttle body out of whack and get an ETC light.
