NHTSA Complaint #716257 — 1996 CHEVROLET S10

ENGINE SPEED WILL INCREASE FROM IDLE TO 2400 RPM WITHOUT THROTTLE INPUT. THIS CONDITION HAS OCCURRED BOTH WHEN THE VEHICLE IS IN MOTION AND WHEN THE VEHICLE IS STOPPED. WHEN IN MOTION, THIS CONDITION CREATES A SUDDEN ACCELERATION PROBLEM. THE ONLY WAY FOR THE DRIVER TO GET ENGINE CONTROL BACK FROM THE COMPUTER (?) IS TO SHUT OFF ENGINE AND RESTART. THIS IS AN ONGOING PROBLEM - FOR A YEAR NOW - AND OCCURS SEVERAL TIMES A WEEK. I HAVE TAKEN THE VEHICLE TO THE LOCAL CHEVROLET DEALERSHIP, BUT WAS TOLD THAT THEY WERE UNABLE TO DIAGNOSE THE PROBLEM BECAUSE THE ENGINE CHECK LIGHT LIGHT HADN'T COME ON. I HAVE ALSO E-MAILED CHEVROLET ABOUT THIS PROBLEM SEVERAL MONTHS AGO, BUT HAVE RECEIVED NO REPLY OR ACKNOWLEDGEMENT. ASIDE FROM BEING AN INCONVIENIANCE, THIS PROBLEM WITH THE ENGINE SPEED CONTROL IS CONTRIBUTING TO EXCESSIVE BRAKE AND CLUTCH WEAR, AND HAS THE POSSIBILITY OF PUTTING THE VEHICLE OUT OF CONTROL WITH POSSIBLE ASSOCIATED LOSS OF LIFE. PLEASE HELP. I HAVE READ OF SIMILAR PROBLEMS WITH OTHER 1996 S-10'S THAT SEEM TO BE RELATED TO A BAD COMPUTER PROGRAM IN THE PCM COMPUTER. CHEVY DON'T SEEM TOO INTERESTED IN HELPING OUT, SO YOU'RE MY LAST HOPE IN GETTING THIS PROBLEM ADDRESSED. THANK-YOU. *AK
