I read an article from the Chicago tribune titled "sticky throttles." I have a 2003 Mercury Mountaineer and the unintended acceleration happened to me on July 13th. I was coming to a stop at a stop light and just as I was about to a complete stop, with my foot on the brake, it tried to accelerate and then stopped. So you may also want to look a the 2003 model also. The article I mentioned is below. Sticky throttles Chicago (Chicago tribune)--the National Highway Traffic Safety Administration is investigating 690,000 2002 Ford Explorer and Mercury Mountaineer sport-utility vehicles after complaints of sticking throttles and unintended acceleration. The Agency's preliminary investigation of vehicles with 4- liter, 6-cylinder engines was prompted by 15 complaints. NHTSA is investigating 2003 and 2004 Ford mustang, mustang convertible and mustang gts after complaints of accelerator pedal interference with the car's carpet. The probe involves about 20,000 mustangs. NHTSA investigations can lead to vehicle recalls.
