I have a 2010 5.4 and thee seems to be a deadspot around 1800-2000 rpm,, sometime it seems fine but other times not so much,,, I know this is drive by wire but is there an accelerator pedal position sensor or possibly replace the throttle position sensor ?

 

There is a pedal position sensor on the pedal, and there is a servo on the throttle body that operates the throttle plate in addition to the throttle position sensor. The throttle body may be dirty and need cleaning. It needs to be removed to clean it, and DO NOT MOVE the throttle plate with the servo physically connected.

 

Thank you,,, so which one would be he most likely culprit for a dead spot on throttle response.... Truck has 60k on it
