the 360 Modena's diagnostic computer shows p1149 and p1189 on right hand ECU. (potentiometer out of range) I hooked up diagnostics computer again. 100% pedal is 3.75v, 0% pedal is 0.75v. According to the error code list, they are within range. Moving forward, I replaced gas pedal potentiometer, then replaced both throttle bodies, then cleaned gas pedal potentiometer connectors, then disabled the immobilizer, then replaced both ignition ECUs. Still get to limited to 20% throttle after a dozen miles or so. What's next? Any other possibilities?
