MY CAR STARTS FINE THEN RUNS OK FOR A FEW MILES AND THEN STARTS JERKING. ONCE I COME TO A STOP IF I HAVE DRIVEN IT LESS THAN 10 MILES IT WILL KILL BUT USUALLY STARTS BACK UP, ANY DISTANCE FARTHER AND IT WILL NOT START UNTIL IT HAS RESTED 20 MINUTES OR SO. SO FAR THE FOLLOWING PARTS HAS BEEN CHANGE, FUEL PUMP AND RELAY, INJECTOR O RINGS, IAT SENSOR, IDLE CONTROL VALVE, EGR VALVE, THROTTLE POSITION SWITCH, GAS FILTER, FUEL PRESSURE REGULATOR. I WAS TOLD THAT THE MASS AIR FLOW SENSOR AND EGR VACUUM SOLENOID WAS RULED OUT AS A POSSIBLE CAUSE. ANY OTHER IDEAS OTHER THAN LETTING THE DEALER KEEP IT FOR A MONTH AND DRIVING IT INTO A RIVER WOULD BE APPRECIATED.
