we are certified by ASE. There are 9 areas that we must pass in order to be considered a master tech. any less and you are a technician. ask to see there certifications if you doubt them.
there is no re learn for the throttle body. the fly by wire system has 2 motors on the body itself and a sensor and module on the accelerator pedal assembly. it learns itself at start up.

what issue do you have??
