Poor engine performance - '02 Ranger 3.0L
Sorry guys, I know the subject is like beating a dead horse, but bear with the new guy... ;o)
The camshaft sensor was the most likely cause of my idle/lack of engine performance troubles so I replaced it this afternoon. I left the negative cable off, as noted in earlier conversations, for about 45 minutes. Cranked the ole girl up and it didn't do much good. I can tell it is not as shaky as before, but it is still unacceptable for a fairly new vehicle (38k miles).
Code for the Check Engine light said 'Cyl. 4 misfire.' She's got new Motorcraft plugs and wires that the previous owner put on...maybe a bad gap setting??
Any ideas on what to replace/check next would be greatly appreciated. Thanks in advance!!
PS - Awesome website!

If I were you I would replace both the plugs and wires(whole set) because it is fairly cheap and is quite easy to do with a small 6 cyl. with low miles. If that doesnt clear up the problem, you might want to look into a faulty coilpack.
