Angry 1991 300e limp home mode

I HAVE A 1991 300E WITH ASR. THE CAR IS GOING INTO LIMP HOME MODE AFTER ABOUT 2 HOURS OF OPERATION.I DO NOT GET AN "ASR" LIGHT!I HAVE CHANGED THE THROTTLE POTIOMETER WHICH DID NOT HELP. I REMOVED THE THROTTLE ACTUATOR FOR TESTING AND FOUND THE FOLLOWING : THE ACTUATOR OCCILATES ERATICALLY AT FULL THROTTLE. LEAVING THE SYSTEM POWERED UP(IGNITION ON ,ENGINE OFF,ENGINE COLD)THE TRAVEL OF THE THROTTLE ACTUATOR SLOWLY DEGRADES UNTIL IT IS "0"! I DISASSEMBLED AND CLEANED THE COMPONENTS OF THE ACTUATOR AND GOT NO IMPROVMENT. I BELIEVE THAT THE ACTUATOR COULD BE BAD BUT AM NOT SURE!ANY HELP WOULD BE GREATLY APPRECIATED! THANKS,DAN
