OVER THE COURSE OF SEVERAL MONTHS THE ENGINE SEEMED TO REV UP WHILE THE BRAKES WERE APPLIED FOR A STOP. ON JULY 29,2013 I TOOK THE CAR TO A RELIABLE SERVICE CENTER AND ASKED FOR AN ANALYSIS OF WHAT THE CAUSE COULD BE. ANALYSIS RESULT INDICATED THAT THE THROTTLE BODY ASSEMBLY WAS THE PROBLEM. A NEW ASSEMBLY WAS INSTALLED, AND I WAS INFORMED THAT FORD HAS A BULLETIN ON THAT PARTICULAR PART ON 2006 GRAND MARQUIS. THE MECHANIC FELT THAT A RECALL SHOULD BE ISSUED FOR SAFETY REASONS.

WHEN PARKING A NEWLY ACQUIRED USED 2006 MERCURY GRAND MARQUIS AT IDLE SPEED IN A LOCAL SHOPPING CENTER, THE ENGINE ACCELERATED AND THE HARDER I PRESSED THE BRAKE THE FASTER THE ENGINE RAN. TO THE EXTENT THE TRACTION CONTROL ACTIVATED AND THE WHEELS SPUN IN PLACE. THE ONLY WAY I PREVENTED CRASHING INTO THREE PARKED WAS TO SHIFT THE TRANSMISSION INTO NEUTRAL WITH THE ENGINE RACING. WHAT APPARENTLY HAPPENED WAS MY FOOT WAS NOT CENTERED ON THE BRAKE PEDAL AND THE PEDAL TRAVELED TO THE POINT WHERE I WAS ALSO PRESSING ON THE ACCELERATOR. EVIDENTLY THE TRAVEL DISTANCE OF THE BRAKE PEDAL WAS SO LONG I PRESSED ON THE ACCELERATOR PEDAL AT THE SAME TIME. I TOOK THE CAR TO A MERCURY DEALER AND WAS TOLD THIS WAS A COMMON PROBLEM, BUT HE COULD NOT CORRECT IT BECAUSE THE BRAKE AND ACCELERATOR PEDALS WERE OPERATING AS DESIGNED. THE DEALERS TECHNICIAN REPORTED THAT MY COMPLAINT WAS THAT THE PEDALS SEEMED TO CLOSE TOGETHER. THIS MAY BE TRUE, BUT THE PROBLEM IN MY MIND IS THE TRAVEL DISTANCE OF THE BRAKE PEDAL. I WAS ALSO TOLD FORD HAS NOT AS YET ISSUED A SOLUTION TO THIS SAFETY PROBLEM.
