customhillbilly Posted August 21, 2012 Report Share Posted August 21, 2012 I have an 03 explorer 4.0 showing multiple misfire codes and an O2 sensor code. From what I have read on the internet it is probably an intake leak but I can't find it. Anyone on here want to take a look at it and not charge me dealership prices? I don't mind paying to get it fixed but can't afford to take it to a Ford dealer I changed the plugs and wires last week and it seems to be getting worse. I haven't been driving it but I could drive it or pull it to a local shop Quote Link to comment Share on other sites More sharing options...
