Re: 1998 Expedition-No Power
Here is the problem. If the check engine light was flashing there was a misfire in one of the coil packs or in the plugs. I have a 1999 EB 5.4L with 176K on it and I have owned it since it had 55,000 on it. The reason that the light might have went off or there was a consistent problem might be because the moisture settled or burned off. My did this sparatically one like your when I had a bit of moisture in the coil. Upgrade your intake and check your coil paks.
