Jeremy airjer W Posted June 1, 2009 Share Posted June 1, 2009 The first thing I would do is monitor live data on a scan tool to see if there are some clues. Quote Link to comment Share on other sites More sharing options...
Tyler23 Posted June 1, 2009 Share Posted June 1, 2009 90,000 miles wore out, dont think so. good thing you stated that it only had 90,000 on it huh? Quote Link to comment Share on other sites More sharing options...
ratmn218 Posted June 1, 2009 Author Share Posted June 1, 2009 oops, my bad. looked today and it has 97000, i do run a k&n air filter if that helps get some clues.was thinking something with the mass air flow???? Quote Link to comment Share on other sites More sharing options...
theoilman Posted June 1, 2009 Share Posted June 1, 2009 Oil wetted air filters can cause mass air flow sensor problems. (Sometimes vehicle manufacturers will not honor engine / emission systems warranties because of installation of oil wetted air filters.)

Jeremy airjer W Posted June 2, 2009 Share Posted June 2, 2009 If the mass air flow is dirty than it usually causes things to go lean. A cold engine needs to be richer until it warms up. A false lean condition could cause your symptoms. Cleaning the MAF with some MAF sensor cleaner might help. Certainly worth the couple bucks for the cleaner.

ratmn218 Posted June 2, 2009 Author Share Posted June 2, 2009 can i use carb cleaner or brake cleaner ? Quote Link to comment Share on other sites More sharing options...
Jeremy airjer W Posted June 2, 2009 Share Posted June 2, 2009 No carb cleaner.Brake cleaner should be fine but there are a few out there that are super potent. I know the 3M stuff is fine to use as well as the stuff we get in the barrel which I can't remember the name of off hand. Quote Link to comment Share on other sites More sharing options...
Whoaru99 Posted June 4, 2009 Share Posted June 4, 2009 Or perhaps some other sensor giving inaccurate readings...coolant temp sensor, maybe? Quote Link to comment Share on other sites More sharing options...
Jeremy airjer W Posted June 4, 2009 Share Posted June 4, 2009 Or perhaps some other sensor giving inaccurate readings...coolant temp sensor, maybe? Absolutely, that's why monitoring the vehicle with a scan tool during its warm up would be beneficial. Quote Link to comment Share on other sites More sharing options...
