Have Ford Questions? Ask a Mechanic for Answers ASAP
The 2010 F150 is what Ford calls, drive by wire. The gas pedal is connected to the engine by a wiring harness, no more throttle cable. So the gas pedal getting stiff is a little hard to actually happen. You should actually have the engine computer scanned for trouble codes before replacing any parts or doing any repairs. Any auto parts store can do this for you. But I would recommend a good repair shop or a dealership to do this. But that is all up to you. Get the trouble codes and post them on this page.
