I would appreciate any help I can get here. I picked up a used series 2 for my 90 stang. I am trying to set this up and calibrate everything. After plugging everything together, I turned the key to the on position to calibrate the TPS. The display reads Idle in the upper right hand corner, but when I open the throttle all the way it still reads Idle. I checked the voltage on the orange TPS wire and it reads .99v when throttle is closed and 4.8v at WOT. Am I doing something wrong, can the TPS still be bad, bad PMS?
