Hi, I recently bought a -96 Sovereign 4-litre, and after some brake and rust- work it was ready for the road.
When driving it seemed a bit slow for 240hp, and we later noticed the throttle not opening fully, even if the pedal was all the way down.
Checking with the computer it confirmed it was only 51% on the TPS.
The throttle cables seemed correctly tensioned (no slack), but when opening the Traction Control Actuator we saw the lower disc/ quadrant (connected to the throttle) stopped moving when the upper disc (connected to the pedal) continued to full. I could manually move the lower disc to full throttle, so it was not stuck.
I am guessing there is something not quite right with the connection (spring?) between the two discs.
Anyone had similar problems, or can shed some light over the actuator design?
