Question about 2004 Mazda 6
While stopped in traffic at a light, with my foot on the brake, transmission in 'D' and engine at idle, the engine rpms suddenly increased sharply and the car started forward. I pushed so hard on the brake pedal that the ABS kicked in, but the car kept moving forward anyway. By the time I shifted into "N," I had lightly bumped the car ahead - no damage to either car. I shut off the engine, waited a half minute, restarted and drove home w/o any problems. I checked for a floor mat jam under the pedal or if my foot could have accidentally been on both pedals at once. Nope. I had just exited a freeway and the car had decelerated and braked just fine. My car has 66,000 mi. This is the second time this has happened. The first was around 14,000 mi. The Mazda dealer found nothing wrong then and it hasn't happened again until now. Is this problem maybe in the "drive by wire" accelerator control system, the throttle body, or just where? I'm afraid of causing an accident if this isn't solved.
Sounds like one of the metal arms connected to the engine may be getting stuck some how. have someone get in car and press on gas when car is off while you watch engine to see what is moving, then check those arms to see if there is any possible obstructions or knicks or something on them

Mine is doing this too! When I notice the car slowing faster than normal when I let off the gas and the brake pedal becoming harder and then it revs and pushes forward in drive while coasting I have to turn it off wait a few minutes and it seems fine
