Consumer Description

FOR 3 TO 5 SECONDS, NO RESPONSE FROM ENGINE AT IDLE WHEN ACCELERATOR DEPRESSED AND THE CAR IS STOPPED (E.G., FOR TRAFFIC SIGNAL). THEN, WITHOUT WARNING, THE ENGINE WENT FROM IDLE (ABOUT 800 RPM) TO RAPID (SURGING) ACCELERATION, OFTEN WITH SCREECHING TIRES. THIS OCCURRED EACH TIME I STARTED FROM A STOPPED POSITION DURING A 493-MILE TRIP. THERE WAS NO PROBLEM AFTER I REACHED MY TARGET DRIVING SPEED. *TR
