NHTSA Complaint #10627245 — 2003 MERCURY SABLE

VEHICLE ACCELERATES ON IT'S OWN. HAVE HAD MULTIPLE PROBLEMS WHERE I GO TO STOP AND CAR ACCELERATES AT A STOP SIGN OR LIGHT. I HAVE ALMOST REAR ENDED MULTIPLE CARS BECAUSE OF THIS. WHILE GOING FROM A RED TO GREEN LIGHT ON A HILL MY SABLE STALLED AND BEGAN TO ROLL BACKWARDS, ALMOST CRASHING INTO THE CAR BEHIND ME, IF IT HADN'T BEEN FOR MY QUICK REACTION. VEHICLE WILL IDLE VERY HIGH, 2.5RPMS AT THE LOWEST, WHILE SITTING IN PARK AFTER STARTUP. AFTER A 5 MINUTES IT WILL SOMETIMES DROP DOWN TO 750-1000RPMS, OTHER TIMES IT WILL CONTINUE TO IDLE HIGH. DURING DRIVE IT WILL CONTINUALLY ACCELERATE TO AROUND 40 MPH ON IT'S OWN. WHEN I BRAKE IT WILL IDLE HIGH AND LURCH FORWARD, UNTIL I'M FORCED TO PUSH THE BRAKE ALL THE WAY TO THE FLOOR. THEN CAR WILL EITHER CONTINUE TO IDLE HIGH OR DROP SO LOW THAT IT STALLS. USUALLY I DRIVE WITH TWO FEET AT LIGHTS OR SIGNS TO BE ABLE TO REV ENGINE FROM STALKING. ENGINE LIGHT CAME ON, CODE READ IDLE AIR CONTROL VALVE, SO IT WAS REPLACED. PROBLEM CONTINUED. TOOK TO GARAGE AND IT LOOKS LIKE THE INTAKE MANIFOLD GASKET. ALL VACUUM LINES WERE REPLACED AS WELL. AM GOING TO FIX THE GASKET AND SELL. CAR SCARES ME TOO MUCH TO DRIVE. MULTIPLE PANIC AND ANXIETY ATTACKS. PLEASE RECALL THIS, EXTREMELY UNSAFE. *TR
