whoops, sorry, my 5.4L had the following:
- #4 and #6 fuel injectors replaced (extended warentee).
- #6 COP
- and ALL spark plugs (with new one peice design).
But just got it back from the dealership and they said #4 has definetly low compression.
I am suspecting the rest of the fuel injectors are lacking in tip-top shape and performance... wish Ford would replace them all for me.
But now I might be leary of the CAM PHASER/s.
(would a bad cam phaser cause ONE cylinder to be bad?)
ps. I am calling Ford hotline tommorrow... this stinks!

I can not get this truck to throw a "check engine light" if I bet it with a stick.
Only one time it threw a code (when the COP finally gave out going up a hill).
But after that was fixed, it is not telling me what is wrong with it.
I may take it to another dealership to get a second opinion...
I didn't call Ford hotline yet, cause I don't want to be a pain in the ***, but it may come to that point.
My truck isn't even drivable, since I live on a hill and it has absolutely no power and I don't want to mess anything else up inside the engine...
Tony.
