05 Cruise Control Issue
I've read threads on inoperative cruise control sets, but mine is a little different...... My cruise works fine at speeds up to 55.... Anything beyond 55, it'll lock on and hold for a few seconds and then start falling off and trying to catch back up. The RPMS will drop and surge back up to speed. It makes the truck feel like it's running out of fuel. Not useable at all at highway speeds.
For clarification, I'm driving an 05 F250 SD, 6.0, Auto Trans, Harley Davidson Edition 4X4. I have jumped out the pressure switch on the Master Cylinder and then road tested with no joy!
Where to start with this one??? Any help will be greatly appreciated!!
