1994 Mercury Cougar acceleration problems

Filed May 15, 2002 · Acceleration, Brakes · PA

Vehicle began spontaneous acceleration while idle and stopped on 10 occasions since 5/1/2002. It took all of my strength to depress the brake to keep the car from jolting forward at a high speed. While pulling into my garage today, travelling at less that 1 MPH, the car accelearated on its own and I had to slam on the brake to prevent from crashing into a heating oil tank. Vehicle has begun to randomly shudder when applying brakes at various speeds from 10 to 65 MPH. This is not a consistent problem but very dangerous when it occurred on highway yesterday. Power window on driver side now randomly shudders when lowering. This is not a consistent problem and is new. The passenger power window is inoperable and too expensive for me to have fixed. This appears to be a very common problem with other owners of this vehicle. The "check engine" light has been on since 1997 and this is also a common problem with this car, from what I understand. I was told that it would cost me $150 to fix and that it is merely a sensor defect and not a afety issue. However, if this is a common problem, ford should over the cost for repair, not the consumer.
