I have a 89 jeep cherokee, 4l auto with 320kms on it and it has a high idle problem.
when i bought the jeep the previous owner had the Idle air control motor unpluged and i pluged it back in and the idle went very high, he told me he had that problem and eventually the idle would go back down and when it does i should unplug it and it will run fine. so i did that and it ran fine with normal idle for a couple years then i lent the jeep to my buddy and he was looking under the hood and pluged the IAC back in and now im having the same high idle problem.
but now it will not go back down and it just staying high
i want to fix the problem but im not sure what to do? is it for the the IAC that is the problem or could it be something else?
should i just buy a a new IAC?
im new to doing anything having to do with electronics on a vehical but i would like to figure out how to trouble shoot this problem. can i figure out what is causing the high idle with a multimeter? if so what setting and what am i looking for??
Thanks
