I backed out of my driveway onto the road. i shifted from reverse to drive. i put my foot on the gas pedal and did not experience typical acceleration. i took my foot off the gas pedal completely. then i put my foot back on the gas pedal and pushed down harder than normal to see if i got a response. at this point the engine began to rev. then i had to put my foot on the brake to prevent the car from moving forward. even with my foot on the brake the engine continue to rev and the car was still moving forward. i put the car in neutral and with my foot off the gas pedal the engine continue to rev. i then depressed the gas pedal with my foot briefly and took my foot off and the engine stopped revving at this point. i put it in drive and had no problems with it after that point. while the vehicle was revving my left foot was not touching or near the gas pedal. the floor mat was not in the way. and my right foot was free and unencumbered. there was no traffic around me so i was able to fully concentrate on the issue and did not hit anyone or anything. *tr
