2008 Mercury Mariner vehicle speed control problems

“2008 MERCURY MARINER THROTTLE CONTROL POWERTRAIN LIGHT COMES ON, TRANSMISSION CANNOT GO INTO GEAR PROPERLY, IT STOPS AT 4000 RPM, AND IT STRUGGLES TO GO AT HIGHER SPEEDS,”

“I REALIZED SOMETIME LAST YEAR THAT MY THROTTLE WAS STICKING WHEN I WOULD START THE CAR AND BEGIN TO TAKE OFF. IT WAS HERE AND THERE AND THEN I MUST HAVE GOTTEN USE TO IT BUT NOW IT DOES IT EVEN WHEN I'M DRIVING, IT STICKS ALL THE TIME. NOW IT DOESN'T WANT TO SHIFT AT THE RIGHT TIMES AND IT ACTS WEIRD A LOT, GOING UP HILLS, WHEN SHIFTING FROM GEARS AND SO ON.”

“TAKATA RECALL WELL DRIVING MY VEHICLE LOST ACCELERATION.WHEN I STEP ON THE GAS THE VEHICLE DIDN'T ACCELERATE AS THE RPM WENT UP.I WAS COMING TO A STOP LIGHT ON CITY STREET.AS I MADE THE STOP AT STOP-LIGHT AS THE LIGHT TURN GREEN I STEPPED ON THE HAS AND THE RPMS WENT UP BUT VEHICLE BARELY MOVED.”

“THE THROTTLE IS HELD OPEN WHEN THE CRUISE CONTROL IS EMPLOYED BUT REMAINS OPEN WHEN THE CRUISE CONTROL IS TURNED OFF BOTH BY USING THE OFF BUTTON AND BRAKE APPLICATION. THIS HAPPENS AT 75-80 MPH ON INTERSTATE HIGHWAYS IN AZ AND UT. THE POWER BRAKE BOOSTER IS INEFFECTIVE WITH NO INTAKE VACUUM. THIS IS VERY DANGEROUS.”
