I have an 1998 F-150, 4.6L 5 spd, a/c, Power windows-Doors, and cd-fm-cassette. The first problem is that the check engine light stays on. I had it checked and the EGR valve was the supposed culprit.! I got a new one and the light still is lit up! After about a 1000 miles I pulled the Battery Cables to reset the computer. After about 20 miles It lit back up and the diagnoses was the same! Any suggestions?
The pther problem is that My dash lights went out which caused the tail lights to go out as well. After sometime because of the many fuses, I found the bad fuse and replaced it. During that time, I found 2 other blown fuses and I replaced them as well. But I have no idea what the fuses controled. There was no change in anything. I have looked all over hell and Half of Montana trying to find some kind of fuse guide to tell me what circuits the fuses control. There is no info in the truck. Can you tell me where I can get a reference to all of the fuses?

Thanx!
Paul
