harriss Posted March 16, 2012 Report Share Posted March 16, 2012 I was driving at about 3/4 throttle from stop to about 70 mph. Engine light came on with codes P0101, P0131, P0151. MAF sensor and lean conditions. I just replaced the spark plugs with AC Delcos. I dont think the plugs have anything to do with the codes, but I guess there is a chance. I used some dielelectric grease and anti-seize on the plugs. Where do I start trouble shooting? Does cleaning the MAF actually do anything? Im curious as to why all three codes came on at the same time. Thanks Quote Link to comment Share on other sites More sharing options...
SSenvy Posted March 17, 2012 Report Share Posted March 17, 2012 Are those other codes o2 sensor codes? If so. Clean your MAF sensor.... fixed mine. I was dealing with those codes for 4 months and cleaned it.... gone! If your running K&N filter, expect to have to clean that thing often. Give it a shot, MAF cleaner is about 8 bucks at yor local ato parts store, and it surely cant hurt. Let us know how it turns out. Quote Link to comment Share on other sites More sharing options...
harriss Posted March 17, 2012 Author Report Share Posted March 17, 2012 Yes the other codes are o2 sensors. I get some MAF cleaner, and try to get code to come on. Thanks Quote Link to comment Share on other sites More sharing options...
