#1 of 2 03 Expedition FX4 Random Misfire by garyca Jun 18, 2009 (2:25 pm)
I have a 03 Supercharged Expedition FX4 with 49,000 Miles on it purchase new in 11/2002. A year ago between 45-60mph i get random jerks while my foot is on the gas. Today it suddenly lost power and the engine was missfiring really bad. I shut it off and restarted the engine and it was normal!!Now when I was driving home it was missfiring really bad, but random. In drive it jerks randomly, in park its normal. I had the sparkplugs replaced 4months ago with the E3 diamond fire plugs. Im thinking all 8 coils need to be replaced??? Do any of you have suggestions???? Thanks

Our windshield wipers on our 2000 EB EXP come on sometimes at startup and you have to turn of the truck to restart. Also if you put them on, they will stay on until you restart the car. Back passenger window won't work, sunroof stopped working halfway, cd player won't eject sometimes, ABS light always on and 1st cyl misfire where spark plugs have oil in them. Anyone know how to help with any of these? The spark plugs especially. We have oil in 3 spark plugs and get a bad misfire. Is it coils, tubes? We've already changed the spark plugs.
