1999 Ford F-150 Problems
Ok guys I have a 1999 F-150 5.4, auto, 4x4 and I have 2 problems I need help with PLEASE !!!!!
1st Problem If you hold the accelerator pedal to 1500 rpms it drops to 1200 then rises back to 1500 then drops again, and countinues. If you are under acceleration and reach 1500 rpm the truck shutters and bucks then smoothes out after 1500........... What is going on....?
NOTE : It also smells rich in the exhaust. I had a EGR code, so I replaced it but it must have been a seperate issue.
2nd Problem is my ABS light is on, we have replaced the speed sensor, with no luck. The brakes pulsate while applying them. Wore out a pair of rotors and pads in about 6k miles. Replaced the pads and rotors again and now 2k miles later the brakes are already so nasty they give you a headache while stopping.
Here is the kicker, when the brakes are wet, the ABS light DOES NOT come on & the ABS works properly, as soon as it dries out, bing - the light comes on and the brake pedal start pulsating again and no ABS working.
Thanks in advance-

First problem sounds like when one of my C.O.P's died, once one goes, replace all.
Second problem might be the ABS module or another sensor. There's a way of testing resistance on each sensor to see if ones crap. Which one did you replace, the rear diff one? or a front? Hell, might even be a fuse. Ya, I'd say you got a good one there.
