1 Engine problem of the 2005 Mercury Montego

Failure Date: 01/03/2010

While idling when stopped or when moving slowly, the engine speed suddenly accelerates to above 3500 rpm causing the car to lurch forward unless the brake is firmly applied. The sudden acceleration lasts 3 to 5 seconds. Placing the gear into neutral has no effect on the engine speed. This happens sporadically. In the last 3 months it has happened approximately 7 times. Dealer says the car's computer system reports nothing unusual.

2 Engine problem of the 2007 Mercury Montego

Failure Date: 02/01/2007

Since vehicle was purchased, when shifting from park to reverse or drive, the vehicle will lunge back or forward, even with brakes applied. Have had to push brake pedal harder than what is normal to prevent this from happening. Dealer "could not duplicate problem" when car was under warranty. Car is now out of warranty and I was told the throttle body needs replacement.
