2004 f350 6.0l help please
 

I keep pulling a code U0432 which says that it is Invalid Data Received from the Multi-Axis Acceleration Sensor Module. I called Ford and the parts guy told me it he thinks that it is the Adjustable Acceleration Pedal that needs replaced. 750 bucks, YIKES!!! THe truck runs good sometimes and other times it feels like it is governed and can't pick up speed. Also, when doing this the Turbo kicks in at about 2500 RPMs and then just takes off. If I step on the throttle it just drones up until the RPMs get high enough for the turbo to kick in. I am sick of dealing with this problem and really need some help if anyone has some suggestions I would appreciate them.
