I have a 91 300e with asr.The output of the throttle actuator slowly decreases over time until the car goes into limp mode.I've replaced the throttle pot(R-25) and the throttle actuator with no results.Can the brake switch,wheel speed sensors,coolant temp sensor , park sensor possibly be causing this. I'd be very happy to PAY some one who is an expert on these early e-gas systems for their time to help me trouble shoot this problem.
Any help or recommendations would be greatly appreciated!
