Guest duke Posted July 6, 2004 Share Posted July 6, 2004 Is the idle speed measured when the car is in "Park" or when it's put in "Drive" but standing still? What should the idle speeds be for both of those states? Thanks! Link to comment Share on other sites More sharing options...
lewisnc100 Posted July 6, 2004 Share Posted July 6, 2004 700 +- 50 rpm in "N" position for A/T when engine is warmed up. Link to comment Share on other sites More sharing options...
Guest duke Posted July 6, 2004 Share Posted July 6, 2004 Should A/C operation affect the idle speed? Link to comment Share on other sites More sharing options...
Guest duke Posted July 9, 2004 Share Posted July 9, 2004 Oh come on.... I know it's a boring question, but please! :help: This is what I've found after warming up the truck: A/C Off: Neutral: ~750 Drive: ~675 AC/ On: Neutral: ~950 Drive: ~750 Do these numbers look within range? The A/C On Neutral setting seems high, and that's the one I am concerned with the most. Thank you! - duke Link to comment Share on other sites More sharing options...
big_johnson Posted July 10, 2004 Share Posted July 10, 2004 I'm not sure what they are supposed to be exactly, but I wouldn't worry about your speeds if I were you, anything under 1000 at idle w/ or w/out AC doesn't seem to be a cause for concern. I think mine also idles a bit high with AC on, butI haven't really paid attention. Anyways, my car idles at about 1300 when its cold in the mornings Link to comment Share on other sites More sharing options...
sw Posted July 12, 2004 Share Posted July 12, 2004 ac will certainly cause different idle speeds as Big J said not really much to worry bout unless something really wrong Link to comment Share on other sites More sharing options...
Guest duke Posted July 12, 2004 Share Posted July 12, 2004 My questions came up after performing the throttle body cleaning with carb cleaner and without removing the throttle body first. I read on the AC Pathfinder newsgroup that resetting the ECU helped some people in restoring the proper idle speed *after* doing the cleaning. I went for the straight-dumb approach of disconnecting the battery, and the car definitely idles lower now. I havent taken down the numbers all around, but idling near or above 1000 is a thing of the past. The anal part of me is now happy and will seak to fix/improve other aspects of this fine automobile.
