Default Need help with M8 throttle problem

Hoping some one can help me with this.
I have an Airtronics M8 radio, it has a Spektrum module and the car has a Spektrum receiver with a Hitec HS-645MG throttle servo.
When I press the throttle on the M8 by about 1/16th of an inch total movement the servo moves about 80% of it's total movement.
Basically when im driving the car I have no real throttle control...I go from no throttle to full throttle by barily touching the trigger.

I have tried a different servo, same issue.
I have tried clearing the profile in the M8 and setting all the functions back to 0...same issue.
I connected a different radio and receiver to this car and do not have this issue.
Whats wrong with my M8?

Sounds like the transmitters throttle pot (inside the radio) has gone bad.
