Re: 05 mountaineer missing
Which engine does your Mountaineer have? When you changed the plugs, did you notice any spark plugs that looked different from the others? Also, regarding diagnostic codes, did you check for pending diagnostic codes or only active codes? There could be a pending code for a cylinder misfire or lean/rich code that is not yet active.
Have you also checked the intake air tubing to make sure there are no cracks in the tubing and that it is connected properly? You might also want to clean the MAF sensor. -Rod |
