THE PROBLEM IS WITH THE GAS PEDAL, ITS HARD TO PRESS/ACCELERATE AND SOMETIMES WHEN I PRESS/ACCELERATE FROM A STOP AND AT SPEEDS OF 30 MPH, IT GETS STUCK AND I HAVE TO PUT IT IN NEUTRAL. VERY DANGEROUS SITUATION. *TR
DRIVING THE CAR IN COLD WEATHER THE THROTTLE WOULD STICK FOR THE FIRST COUPLE OF MILES UNTIL THE CAR WAS WARMED UP. THIS IS A 4CYL.AUTO TRANS./ SAME TYPE OF VEHICLE AS FORD ESCAPE. *TR
I OWN A 2005 MERCURY MARINER, PURCHASED NEW. WHEN IT GETS COLD THE GAS PEDAL STICKS, I PUSH DOWN AND THERE IS NO RESPONSE FOR A FEW TIMES. THIS ALMOST CAUSED ME TO BE REAR ENDED THIS MORNING HAD I NOT PUT ON THE HAZARD LIGHTS. ONCE IT WARMS UP IT IS FINE. THIS HAS BEEN GOING ON SINCE I BOUGHT THE CAR BRAND NEW IN 2005. THIS HAS HAPPENED OVER 50 TIMES AND IS STARTING TO SCARE THE HECK OUT OF ME. *TR
