WHILE DRIVING ON THE HIGHWAY AROUND 55MPH THE CAR WOULD SUDDENLY LOSE THROTTLE RESPONSE. ALL THE ENGINE LIGHTS WOULD COME ON AND THE CAR WOULD SHAKE VIOLENTLY UNTIL I TURN IT OFF AND THEN BACK ON. ONCE I DO THAT THE CAR DRIVES BUT SHIFTS VIOLENTLY. WAS TOLD IT WAS A PCM FAILURE. OCCURS MORE OFTEN IN COLD WEATHER. IT HAPPENS SO OFTEN THAT WHILE ON THE HIGHWAY I QUICKLY PUT IT IN NEUTRAL SHUT IT OFF AND TURN IT BACK ON WHILE STILL ON THE HIGHWAY. *TR
