I had my check engine light go on last night i took it to the local Autozone to havethe diagnostic test done it shows a misfire on # 3 they told that could be a number of things. Also i smelled something that smelled like fireworks coming thru the vents and noticed the smell on the passenger side ofthe motor couldthis be related? I could feel the truck shaking a little bit too when i would step on the gas.
I just had the same problem and our mechanic said that 95% of the time if you changed the spark plugs and wires it would eliminate the problem. He also said that 1998 Expeditions were notorius for leaking anit-freexe into that particular spark plug by the hose that runs above it. We did as he suggested plus tightened the clamp on the hose to keep the anit-freeze from dripping and have had no problems since. The check engine light went off and it runs like a champ again with 135,000 miles!
