1997 GMC Sonoma Fuel system Problems

VEHICLE THROTTLE STICKS AT 1500RPM AND WILL STICK ABOVE 1500RPM IF DOWNSHIFTED OR INCREASING SPEED. THE ONLY WAY TO LOWER THE RPM TO IDLE IS SHIFT TO NEUTRAL A N D COME TO A COMPLETE STOP -- FIRMLY HOLDING BRAKE TO MAXIMUM DEPRESSION AND THEN ONLY AFTER A FEW SECOND DELAY. UPON ENTERING ANY GEAR [AUTOMATIC XMSN] THE RPM WILL AGAIN GO TO 1500, BUT IF BRAKE PEDAL REMAINS DEPRESSED FOR ABOUT 10SEC THE RPM WILL GO BACK TO IDLE. ANY SLICK ROADS OR MOUNTAIN/STEEP DOWNHILL DRIVING IS EXTREMELY HAZARDOUS! CHECK ENGINE STAYS ON AND COMPUTER READING CALLS FOR REPLACEMENT OF A SENSOR WHICH HAS BEEN REPLACED 3 TIMES. THE DIRECTIONS SAY TO LET THE NEW SENSOR "BREAK IN" BY IDLING FOR 20 MINUTES MINIMUM PRIOR TO DRIVING. IT DOES NOT WORK! THIS IS A FAULTY DESIGN WHEREIN A SENSOR OR COMPONENT MALFUNCTION RESULTS IN THROTTLE BOOST BEYOND OPERATOR CONTROL AND IS OFTEN AT RPM'S ABOVE 2500 !!! THE MALFUNCTION IS PERMANENT AND THE INCIDENT OCCURS EVERY DAY THE VEHICLE IS DRIVEN !!! *TR

WE HAVE A 1997 GMC SONOMA WITH A VOTREC 4.3 X. OVER 2 YEARS AGO, WE STARTED GETTING MISFIRES. WE TRIED EVERYTHING WE COULD THINK OF, TO NO AVAIL. IN THE PAST MONTH I'VE PUT OVER $500 ALONE. I HAVE BEEN LOOKING IT UP ON-LINE, AND HAVE REALIZED, I'M NOT THE ONLY ONE WITH THIS ISSUE. THERE HAS EVEN BEEN A RECALL IN CALIFORNIA, BUT ONLY THERE. GM TOLD ME THEY HAVE DIFFERENT GAS OUT THERE. ANOTHER MAJOR SAFETY ISSUE HAS BEEN THE WIPER MOTOR FAILURE, THAT HAD A RECALL. GM TOLD ME MY VIN # WAS NOT ON THE LIST, BUT I BATTLE MY WIPERS AT LEAST ONCE A MONTH. I HAVE TO YANK THE BLADES HALF WAY UP THE WINDOW BEFORE THEY GRAB AND START TO WORK. ONE MORE PROBLEM THAT I NOW KNOW I AM NOT ALONE ON IS THE ISSUE WITH DEX-COOL. WE HAVE FLUSHED AND REFILLED THE SYSTEM AT LEAST THREE TIMES, ONLY TO HAVE IT GUNK-UP AGAIN. PLEASE HELP ME AND ALL THE OTHER CUSTOMERS WHO GOT TRAPPED WITH JUNK VEHICLES. WE HAVE HAD TOO MANY OTHER FAILURES TO COUNT!*AK

SINCE DAY ONE OF GETTING THE TRUCK, I NOTICE THAT THE GAS TANK METER WAS BROKE. BROUGHT IT BACK IN TO THEM FOR METER PLUS THE BRAKE SYSTEM. THEY FIXED THE METER PROBLEM BUT THEY SAID NEEDED BRAKE PADS CHANGED. SO I WENT HOME CHANGED THE BRAKE PAD, ROTOR, DRUMS. WENT BACK IN EVER SINCE THEN TILL NOW FOR COOLANT, KNOCKING OF ENGINE, A/C, MAIN ENGINE SEAL GASKETS, BRACKETS, FUEL SYSTEM, MOTOR MOUNTS, BELTS, SEALS, NIPPLES, STUDS, FAN CLUTCH, PULLEYS, PLUS BRAKES ARE STILL FAILING,(WENT ON LINE FOUND OUT BRAKES ARE RECALLED THEY FAILED TO TELL ME THAT). AS FAR AS I CAN SEE THE MOTOR IS BAD. THE TRUCK HAS COST ME MONEY OUT OF POCKET, WORK TIME, AS WELL AS MY OWN ON A PERSISTENT BASIS. THE TRUCK IS JUNK.
