2003 GMC SIERRA 2500 Fuelpropulsion System Problems

HAD INJECTORS REPLACED UNDER WARRANTY AT 50000 MILES AFTER NOTICING EXCESS EXHAUST SMOKE ON STARTUP AND ALSO POWER STEERING HOSES WERE LEAKING, AGAIN AT 105000 MILES THEY TOTALLY FAILED AS I WAS BRINGING MY WIFE HOME FROM HOSPITAL ON I-15 IN CA. UP CAJON PASS AND HAD TO BE TOWED TO DEALER, BUT GM DEALER WOULD NOT COVER INJECTORS UNDER WARRANTY AS TRUCK WAS11 YEARS OLD AND THEIR COVERAGE WAS FOR 7 YEARS ONLY, NOW AGAIN HAD TO HAVE THEM REPLACED AT 147000 MILES BECAUSE OF EXCESSIVE SMOKE ON STARTUP. THIS TIME I WENT TO AN INDEPENDENT SHOP AS THEY WERE $1000 CHEAPER AND STATED THESE UPGRADED INJECTORS SHOULD LAST 150000 MILES NOT 50000. HAD TO HAVE POWER STEERING HOSES REPLACED AGAIN ALSO ALONG WITH POWER BRAKE SERVO BECAUSE THEY WERE LEAKING AGAIN AT 157000 MILES. I HAVE ALL OF THIS DOCUMENTED IN WRITING BY SERVICE DEPTS.

BRAKE LINE RUSTED THROUGH AND LOST ALL BRAKING CAPABILITY. LUCKLY IT HAPPENED PULLING INTO MY DRIVEWAY AND NOT ON THE HIGHWAY! FUEL LINES RUSTED THROUGH AND LEAKING FUEL PUDDLING ONTO THE GROUND.

TL* THE CONTACT OWNS A 2003 GMC SIERRA 2500. THE CONTACT STATED THAT AFTER INSPECTING THE VEHICLE, HE NOTICED THAT THE OIL LEVEL WAS ELEVATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE FUEL INJECTORS NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED HOWEVER, THE FAILURE RECURRED AFTER APPROXIMATELY 30,000 MILES AND THE VEHICLE WAS EMITTING SMOKE. THE VEHICLE WAS REPAIRED WITH NEW FUEL INJECTORS BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 209,000.

(ELECTRICAL) AS AN ONGOING ISSUE, THE DASHBOARD GAUGES/INDICATORS (I.E. TACH, SPEEDOMETER, ETC..) WILL SOMETIMES NOT REGISTER UNTIL SEVERAL MINUTES AFTER THE VEHICLE HAS BEEN RUNNING (THIS COULD BE FOR UP TO MILES) IT HAS NOT AFFECTED VEHICLE PERFORMANCE TO DATE. (FUEL/PROPULSION SYSTEM) I HAVE BEGUN HAVING ISSUES WHERE IT GOES INTO "REDUCED ENGINE POWER". FURTHER DIAGNOSTIC ATTEMPTS HAVE LED ME TO BELIEVE THAT IT IS DUE TO A FAULTY THROTTLE POSITION SENSOR (PART OF THE THROTTLE BODY), TAC MODULE, OR APP ASSEMBLY (ACCELERATOR PEDAL). MOST LIKELY CAUSE MAY BE DUE TO THE THROTTLE POSITION SENSOR, AS THIS ISSUE HAS HAPPENED WHEN THE VEHICLE IS ON "CRUISE CONTROL". HOWEVER, DUE TO THE INFERIOR DESIGN OF THE THROTTLE BODY UNIT ITSELF, THE MANUFACTURE HAS MADE IT DIFFICULT OR IF DESIGNED TO BE IMPOSSIBLE TO REPLACE JUST THE TPS, BY RIVETING THE TPS TO THE THROTTLE BODY, AND MAY HAVE TO REPLACE THE...
