Engine Mechanical problem
2003 Ford Expedition V8 Two Wheel Drive Automatic 121000 miles
I've replaced spark plugs, and brought to the shop several times. There weren't any codes for a while to be pulled, but when it finally did, it showed misfire on cylinder 5 (which is one of the ones I replaced). We replaced the coil and plug but still runs terrible. I have no idea where to look next. My mechanic suggested it may be the Catalytic converter, but he doesn't look into those types of issues. I don't want to spend another $100 just getting Ford to look at it. If you have any ideas what some possibilities could be, it would be greatly appreciated.
have the same problem?
