2002 Chevrolet S10

WHEN I TEST DROVE THIS VEHICLE, I "PUNCHED" THE THROTTLE TO CHECK RESPONSE, ENGINE-MISFIRE, SMOKE, ETC. THE THROTTLE STUCK IN THE OPEN POSITION AND THE VEHICLE CONTINUED TO ACCELERATE. REPEATED PUNCHING OF THE ACCELERATOR RELEASED THE THROTTLE AND I WAS ABLE TO REDUCE ENGINE SPEED. THE DEALER INDICATED THAT THIS PROBLEM WAS CAUSED BY CARPETING SNAGGING THE THROTTLE CABLE. (WRONG). THE DEALER EXAMINED THE VEHICLE, DECLARED THE PROBLEM CURED, AND I PURCHASED THE VEHICLE. SINCE THAT TIME, THE THROTTLE HAS STUCK MORE THAN A DOZEN TIMES. THIS IS PARTICULARLY DANGEROUS WHEN ATTEMPTING TO PASS ANOTHER VEHICLE, OR ACCELERATING FROM A TRAFFIC LIGHT. THE THROTTLE STUCK ONCE WHEN I WAS PULLING INTO A DOWNTOWN PARKING LOT. IN ALL THESE CASES, HAD I NOT KNOWN WHAT TO EXPECT, THERE COULD HAVE BEEN AN ACCIDENT. NO PARTS HAVE EVER BEEN REPLACED ON THIS VEHICLE TO THE BEST OF MY KNOWLEDGE. THE FIRST INCIDENT OCCURRED ON AUGUST 21, 2004 AND ANOTHER INCIDENT OCCURRED TODAY (FEBRUARY 25, 2005). *NM

THROTTLE STICKS IN FULL-OPEN POSITION. MOTOR RPM BOUNCE OFF THE REV-LIMITER WHEN THIS HAPPENS. PROBLEM IS NOT IN THROTTLE CABLING OR ACCELERATOR PEDAL MECHANISM. PROBLEM IS INTERNAL TO THROTTLE BODY. FEELS LIKE A PIECE OF RUBBER IS JAMMED BETWEEN THE THROTTLE PLATE AND THROTTLE BODY HOUSING. VEHICLE IS CURRENTLY AT DEALERSHIP BECAUSE OF THIS PROBLEM. *LA

CONSUMER HAS BROUGHT VEHICLE BACK TO THE DEALERSHIP THREE TIMES FOR A CREAKING NOISE HEARD IN THE FRONT END. ALSO, CONSUMER COMPLAINED THAT WHEN TAKING FOOT OFF THROTTLE VEHICLE WILL NOT SLOW DOWN FOR A PERIOD OF TIME. WHEN DRIVING WITH THE AIR CONDITIONER ON, VEHICLE WILL NOT SLOW DOWN. VEHICLE OVERRUNS THE CRUISE CONTROL FROM 3 TO 6 MILES PER HOUR. *JG *JB *NLM. *AK

THROTTLE STUCK IN WIDE OPEN POSITION ON RAMP ENTERING HIGHWAY, BRAKES WERE NOT EFFECTIVE IN STOPPING VEHICLE, SPEED INCREASING , TURNED IGNITION KEY OFF AND COASTED TO STOP, CHECKED ACCELLERATOR PEDAL, WAS STUCK IN WIDE OPEN POSITION, COULD NOT FREE IT, CHECKED FOR INTERFERENCE FROM CARPETING AND THERE WAS NONE, WAITED A WHILE AND THE PEDAL REALEASD ON ITS OWN, DROVE IT HOME UNDER PARTIAL THROTTLE, CALLED THE DEALER, WHO SENT A ROLL BACK TRUCK TOPICK IT UP, WHILE WAITING ON THE WRECKER I DEPRESSED THE PEDAL AND IT STUCK TO THE FLOOR, I THEN TOOK A CAMERA AND TOOK PICTURES OF THE PEDAL IN STUCK POSITION TO SHOW THE DEALER IN CASE HE DIDNT BELIEVE ME. THE PICTURE CLEARLY SHOWS THAT THERE WAS NO INTERFERENCE FROM THE CARPET OR MAT, AS THE ENGINE COOLED DOWN THE PEDAL RELEASED AGAIN, WHICH LED ME TO BELIEVE THAT THE PROBLEM WAS HEAT RELATED AND WAS LOCATED SOMEWHERE IN THE THROTTLE BODY ASS.,DEALER WORKED ON VEHICLE AND STATED ON THE WORK ORDER THAT THE PROBLEM WAS CAUSED BY CARPET PROTECTER INTERFERENCE, TOOK TRUCK HOME AND CHECKED OUT THE THROTTLE BODY ASSEMBLY, THERE WAS CLEAR SIGNS THAT WORK HAD BEEN ATEMPTED IN THAT AREA. RETURN SPRING HAD SIGNS OF TOOL CONTACT, BUTTERFLY IN THROTTLE BODY BORE SHOWED SIGNS OF TOOL MARKS, I CHECKED TO MAKE SURE EVERYTHING WAS FREE, WHICH IT WAS, MY CONCERN IS THAT IF IT IS A REACURING PROBLEM SOMEONE WITH LESS LUCK COULD POSSIBLY BE KILLED AND THE MANUFACTURER IS NOT TELLING THE TRUTH ON THE REAL CAUSE OF THE PROBLEM. *AK
