wranglercory Posted October 20, 2010 Posted October 20, 2010 I need to re-phrase my last post. I previously had a high idle problem that would only go away when the IAC was tapped on pretty hard. I swapped that with another one but now the idle problem is all good but just when its started up it should idle up a little then slowly come down to a steady idle. I was wondering if anyone has any ideas , I was considering removing power to the truck and reconnecting the battery to see if it relearns th eidle position at a cold start up. :???:
Pete M Posted October 21, 2010 Posted October 21, 2010 yes, the IAC controls the idle speed. have you tried cleaning it?
wranglercory Posted October 21, 2010 Author Posted October 21, 2010 The IAC that is on the 2.5 is a completely sealed unit not like th e4.0 that has a plunger style one.The only moving part is the idle stop that rests against the throttle body plate.
