APPLYING THE BRAKES AT A STOP REQUIRES THE BRAKE PEDAL TO BE FIRMLY HELD TO THE FLOOR OTHERWISE THE ENGINE WILL START REVIVING UP AND MOVE OUT FAST IF THE BRAKE IS RELEASED. ALSO APPEARS THAT THE TRANSMISSION WHEN MOVING THE SHIFTER TO PARK DOES NOT MEAN THE CAR IS IN PARK. I DID THIS ONCE IN A STORE PARKING LOT. THE SHIFT HANDLE WAS IN PARK. BUT AS SOON AS I TOOK MY FOOT OFF THE BRAKE AND OPENED THE DOOR CAR TOOK OFF. CAUSED $ 6,700 TO FIX ALL THE DAMAGE. ENGINE DOES NOT COME OFF FAST IDLE. WHEN I FIRST GOT THE CAR. IDLE RPM WAS BETWEEN 500 AND 750. NOW THE IDLE NEVER GOES BELOW 1200-1300 RPM. I TRIED VARIOUS BRANDS AND GRADES OF GAS INCLUDING ETHANOL FREE UNLEADED BUT NOTHING HELPED.
