2009 f150 erratic throttle/surging
Hello, I have a 2009 F150 4x4, XLT crew 6.5' bed, 5.4 engine.
The truck has a very strange erratic throttle behavior from a dead stop through low speeds, shifting seems very strange at low speeds too.
Dealer tried re-flashing the computer, but that didn't fix it. They talk about some valve that sounds to me like it's similar to an EGR function, but I cant remember what he called this valve. He explained the issue as exhaust gasses that are to be recirculated and burned, but the valve is opening at the wrong time, or stuck open or something so it feeds the fire so to speak.
Does any of this sound typical or common?
Is this something that's hopefully easier to do than a spark plug change on a 5.4?
Thanks.<!-- google_ad_section_end -->
