when i worked for ford,left in 2012, and we had a wrench lite come on, ford told us to check codes, overlay thr throttle body wiring harness with homemade harness and if that didn't fix it replace the throttle body.
Sounds expensive.... I'll have to have quote before they "dig in". I'm not wrapping up 1200 bucks in repairs.. I'll part it then scrap it first... Or, slant swap it.. LOL
