I HAVE A 93’ TOWNCAR EXEC. AND HAVING PROBLEMS WITH ENGINE RUNNING ROUGH WHEN REACHING OPERATING TEMP. HESITATION AND HAVING TO KEEP PUMPING GAS PEDAL TO KEEP CAR FROM DYING. CHECK ENGINE LIGHT WILL COME ON BUT NO CODE IS PRESENT. WHEN PARKING ON A DOWNHILL GRADE AFTER REACHING NORMAL OPERATING TEMP, CAR WILL NOT START. IF LEFT IN IDLE , WHILE PARKED ON DOWNHILL GRADE , ENGINE WILL SURGE , UP AND DOWN. IF PARKED LEVEL ,WHEN ENGINE IS OPERATING TEMP AND TRY TO START , CAR WILL SHAKE AND HAVE TO PUMP GAS PEDAL TO KEEP ENGINE GOING. AFTER PUTTING IN DRIVE , AFTER LEVEL START PUSH GAS PEDAL TO THE FLOOR AND NOTHING , HAVE TO PUT IN NEUTRAL AND PUMP THE GAS, AND THROW INTO DRIVE TO GET MOVING AGAIN. ONCE MOVING IT WILL RUN FINE. ANYBODY OUT THERE WENT THROUGH THIS WITH THEIR LINCOLN? THANKS GUYS
