Driving on the freeway today I had to pass another car. I gave full throttle and passed the car but when I let off the throttle it was stuck. I had the tranny in normal drive mode not manual and no cruise control. Also the floor mat was not stuck on the throttle. I had one foot on the brake while I tried engine braking in manual mode. Also tried canceling cruise control and tapping on the throttle. Nothing was working untill the car just decelerated on its own. This of course scared the s*it out of me. I have not given the car full throttle since. I am getting ready to take the car from LA to Vegas this weekend. This has never happened before, should I take the car in for a diagnostic check?
