Driving on city street at about 30-35 mph. as i approached intersection i took foot off accelerator pedal and stepped on brake pedal to slow down and stop at intersection. as i stepped on brake pedal, i could hear engine start accelerating and car wouldn't stop. i noticed tach reading between 4 and 5. although engine was accelerating and vehicle was moving forward it was not moving at excessive speed. i pressed harder on brake pedal and while car slowed somewhat it would not stop. so i decided that the only way to stop vehicle was to move gear shift lever to park and then turn off engine. i then restarted car and it functioned normally. my experience might be an example of what has been called "sudden, unintended acceleration". *tr
