702_MJ Posted November 16, 2009 Share Posted November 16, 2009 I got an idle problem that comes and goes. It will go away after warming up (its my DD and I don't want to drive it and get stuck at college) , but it throws like 5 codes... The ones that concern me is MAP sensor circuit and then it brings up O2 sensor circuit. The MAP came off another cherokee cuz it screwed up once before and I just swaped it on(if it worked don't fix it kinda scenario). But I had a feeling that the used one would fail soon, its actually been like 6months. And I don't think the O2 sensor has ever been replaced.................... Should I just go buy the O2 and MAP and see where I am when the dust settles? Link to comment Share on other sites More sharing options...
Automan2164 Posted November 16, 2009 Share Posted November 16, 2009 I would... I mean, if they are the originals, not only would it probably help your problem, it would be good maintenance. Rob L. Link to comment Share on other sites More sharing options...
