2004 Chevrolet Colorado

VEHICLES CHECK ENGINE LIGHT CAME ON THEN WENT OFF AFTER A COUPLE OF DAYS. VEHICLE IDLE DROPPED TO 500 RPMS. THE TRUCK STARTED TO ACT SLUGGISH AND ACTED AS IF IT WOULD SHUT OFF AT IDLE. DURING ACCELERATION THE VEHICLE WAS AGAIN SLUGGISH. TOOK THE TRUCK TO A LOCAL SHOP AND HAD THE CODES RUN. IT CAME BACK AS AN ENGINE LOW RPM CODE. I DON'T RECALL THE ACTUAL CODE NUMBER. HAD THEM DO A MOTOR VACUUM TO CLEAN THE FUEL SYSTEM AND RESET CODE. THE CHECK ENGINE LIGHT HAS GONE AWAY AND HAS NOT COME BACK ON. VEHICLE DOES FROM TIME TO TIME ACT AS IT IS GOING TO BOG DOWN. I THOUGHT THAT I SHOULD SUBMIT THIS COMPLAINT BECAUSE IT SEEMS THERE ARE SEVERAL OTHERS WITH THE SAME PROBLEM.*AK

THE CHECK ENGINE LIGHT COMES ON ACCOMPANIED BY AN ENGINE MISFIRE DUE TO WEAK EXHAUST VALVE SPRINGS WHICH MUST BE REPLACED. RECENTLY GMC ISSUED A BULLETIN TO THEIR SERVICE DEPARTMENTS ADVISING MECHANICS ON THE ISSUE, AND RECOGNIZING THE PROBLEM WITH THE VALVE SPRINGS AND HOW TO FIX IT, BUT WILL NOT ACKNOWLEDGE A MANUFACTURER'S DEFECT. ACCORDING TO THE BULLETIN THIS PROBLEM OCCURS IN ALL CHEVROLET COLORADOS 2004-2006, GMC CANYONS 2004-2006, AND THE HUMMER H3. THE ESTIMATED COST OF REPAIR IS ABOUT $2000, QUOTED BY THE DEALER MECHANIC. NOT ONLY DOES THE CHECK ENGINE LIGHT COME ON AND STAY ON, IT ALSO CAUSES THE VEHICLE TO STALL WHILE IN OPERATION. THE TRUCK SHUT DOWN IN THE MIDDLE OF THE INTERSECTION WHILE DRIVING. ADDITIONALLY YOU WILL HAVE DIFFICULTY WHEN YOU START YOUR CAR, IT WILL MISFIRE AND YOU MAY HAVE TO RESTART AGAIN. THIS WILL BEGIN TO HAPPEN REGULARLY UNTIL YOU DIAGNOSE THE PROBLEM. I WENT TO DIFFERENT DEALERS TO DIAGNOSE THE PROBLEMS BECAUSE DIFFERENT MECHANICS COULD NOT FIND THE PROBLEM WITH THE CHECK ENGINE LIGHT. THE LAST STEP WAS A DEALER MECHANIC THAT HAD JUST RECEIVED THE ABOVE MENTIONED BULLETIN. THEY DID NOT FIX THE PROBLEM WITH THE VALVE SPRINGS, INSTEAD THEY RESET THE COMPUTER TO STOP THE CHECK ENGINE LIGHT FROM OCCURRING. THE MISFIRING AND STALLING CONTINUED TO HAPPEN.*AK

DT*: THE CONTACT STATED THAT WHILE WAITING AT THE TRAFFIC LIGHT, THE ENGINE RACED AND ACCELERATED AS IF IT WAS ENGAGING TO 50 MPH. IN AN ATTEMPT TO PROHIBIT THE VEHICLE FROM ACCELERATING, THE CLUTCH WAS ENGAGED WHILE DEPRESSING THE BRAKE PEDAL. THERE WAS ALSO A SULPHUR SMELL INSIDE THE VEHICLE. THE VEHICLE WAS TAKEN TO A SERVICE DEALER WHO WAS UNWILLING TO REPAIR THE VEHICLE WITHOUT A FEE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC SHOP WHO DISCOVERED TWO TROUBLE CODES ON THE DIAGNOSTIC COMPUTER SYSTEM. THE FIRST WAS A PO300 RANDOM MISFIRE CODE. THE SECOND WAS A P1133 FRONT OXYGEN SENSOR SLOW AND SWITCHING CODE. THE CHECK ENGINE LIGHT FROM THE PANEL WAS ALSO CONSTANTLY ILLUMINATED. THE ISSUES HAVE GRADUALLY WORSENED SINCE THE VEHICLE WAS PURCHASED.

2004 COLORADO TRUCK STALLED WITHOUT WARNING AT 70 MPH WHILE GOING UP A STEEP INCLINE. *TS THE VEHICLE'S SPEED DROPPED FROM 70 TO 15 MPH WITHIN SECONDS. THE CONSUMER WAS UNABLE TO PULL OVER BECAUSE THERE WAS NO SHOULDER. THE CONSUMER LOOKS AT THE INSTRUMENT PANEL AND NOTICED THAT THE DIC WAS FLASHING REDUCE POWER. THE CONSUMER LATER FOUND OUT THAT IF THE VEHICLE ENCOUNTERS A LITTLE EMISSION PROBLEM IT SHUTS DOWN. THE CONSUMER'S VEHICLE DIDN'T HAVE AN EMISSION PROBLEM BUT A COMPUTER GLITCH. *NM
