Three problems related to accelerator pedal have been reported for the 1999 Mercury Mountaineer. The most recently reported issues are listed below.
Accelerated 1999 Mercury Mountaineer v8 from stop light. Throttle got stuck in accelerate position. Tried to free throttle by repeated pulsing with foot but acccelerator stuck in full throttle position and could not stop car! had to turn off ignition resulting in no power steering or braking. Was able to free throttle by removcing throttle cover (on engine) and manually moving throttle by hand. Would have hit car in front of me if there was traffic! throttle plate assembly replaced by authorized Ford dealer at my cost.
While driving there was unattended acceleration. Consumer's foot actually was on the brake and at the accelerator pedal at the same time. The pedals were very close together. Accident occurred. Vehicle was totaled. Upon impact, the air bags did not deploy. . . . . . Once off the exit ram slid through grass an dinto pine tree.
Gas pedal sticks intermittently. Forcing pedal causes vehicle to surge/dealer check said no problem found at this time. Prior to taking to dealer I attempted lubrication in interior and under hood. Seemed to stop problem for 30 minutes to an hour, then intemittant sticking returned.
