Question about 2003 Ford Expedition

1 Answer

My 97 expedition has a miss fire. was told by canadian tire that it was something wrong with the engine, meaning it was no longer any good. i changed the coils and the wires as well as the plugs, the vehicle got better but not smooth it still has a miss. when i changed the plugs i noticed that there were a few that appeared green in color as if it was burning anti freeze but it is full in the bottle. was told it may be the valves in the head due to carbon build up. i bought this rig for my wife and would like to know for sure what is wrong. is it spark, is the motor gone, is it the dome gasket, or is it burning coolant.

First off, I would get a second opinion (and not put alot of faith in C/T) I would get the cooling system pressure tested & checked for leaks internal & external to eliminate bad head gasket or cracked coolant passage way. (If it had an internal leak - plugs would be wet and you would see white smoke from exhaust) RE; miss - run a really good/strong fuel system cleaner through it (Seafoam,STP, Gumout) and then change fuel filter.

My 2003 Ford Expedition runs rough at idle and the service light started blinking.

it sounds like you need to tune up your vehicle. whenever the service light blinks it usually means you have a miss fire. You can take it to auto Zone to retrieve the code. The code should tell you what cylinder is miss firing.Hope this helps. Please leave comment.

Engine misses at idle and after shifting (Jetta 97)

Did you by chance check the resistance of your plug wires? They have a tendency of breaking down over a period of time and need replaced. The spark plugs would have told you what was wrong with the engine many times.

Either a burnt bulb, or a fuse. The check engine light has nothing to do with the radio.

Plug in your car and listen for a "sizzle" sound. If you hear this then your block heater works.... if not..... Call Canadian Tire!
