2004 Nissan Frontier Fuel system Problems

This is the first major safety incident with a stuck and wide-open throttle. I just started from a left hand turned at a stop light. I noticed the 2004 Nissan Frontier pickup truck began to increase its speed without any extra pressure applied to the gas pedal. I applied the brakes to slow down the truck's speed while the engine continued to increase speed. I turned on the flashers to warn traffic. I put the truck into neutral while braking and the engine immediately revved to high and loud rpms. I heard the engine making a shift in its high rpm revving noise, and I turned off the engine. I was now fully stopped near the curb. Next, my husband started the engine after a few minutes of being stopped. The engine immediately started revving to the high rpms. Since the truck was parked, he tapped the gas pedal a few times which seemed to reset the engine's wide-open throttle. Safety Issue: The engine revved to very high rpms and speeded up on its own; brakes were not fully stopping the truck. Failed Component: The engine's "throttle"

THIS TRUCK HAS BEEN WORKED ON MULTIPLE TIMES FOR RUST, CORROSION, GAS TANK LEAKS, BEARINGS AND REAR DIFFERENTIAL. IT CONTINUES TO RUST AND CORRODE. THE MOTOR RUNS WELL BUT THE VEHICLE HAS RUSTED EVEN WITH EXCELLENT CARE. I AM SO DISAPPOINTED. THE GAS TANK HAS BEEN FIXED MULTIPLE TIMES AND CONTINUES TO CORRODE AND LEAK. I THINK THAT ALL OF THESE ISSUES NEED TO BE CHECKED ON. THE REAR DIFFERENTIAL HAS CORRODED AND ALL OF THESE ISSUES ARE VERY EXPENSIVE EVERY TIME THAT IT HAS TO BE FIXED. I WOULD APPRECIATE YOUR HELP WITH THESE PROBLEMS.

TRUCK TOTAL MILEAGE IS ONLY 55,000 AS IT IS NOT USED VERY MUCH. 3 ISSUES OCCURRED APPROX. AT 49,000MILES. 1) ENGINE STARTED TO MISS. UPON CHECKING SPARK PLUGS IT WAS DISCOVERED THAT THE PLUG CAVITIES IN THE HEAD WERE FULL OF OIL. THE VALVE COVER GASKET SEALS HAD LEAKED AND THE OIL FILLED SPARK PLUG HOLES CAUSED IT TO MISS. THIS IS NOT COVERED UNDER WARRANTY SO REPAIRS WERE DONE AT MY COST. HAD TO REPLACE ALL OF THE TOP END VALVE COVER GASKET AND SPARK PLUG HOLE SEALS AS WELL AS THE CAM END SEALS. 2) ONE DAY I GOT INTO THE TRUCK AND WHEN I STARTED IT UP AND PRESSED THE BRAKES THE PEDAL WENT TO THE FLOOR. UPON CHECKING THE BRAKE MASTER CYLINDER RESERVOIR IT WAS EMPTY. FOUND THAT THE REAR AXLE BRAKE LINE HAD RUSTED THROUGH AND HAD BURST SPRAYING BRAKE FLUID ALL OVER THE SPARE TIRE. I HAVE NEVER SEEN A BRAKE LINE DEVELOP A HOLE LIKE THIS. NOT COVERED UNDER WARRANTY AND A NEW BRAKE LINE AND MASTER CYLINDER WAS REPLACED AT MY OWN COST .THE SYSTEM HAD TO BE BLED OUT AND FLUSHED AT ALL 4 WHEELS. I WAS VERY LUCKY THAT THIS DID NOT OCCUR WHILE DRIVING AS A CRASH WOULD HAVE RESULTED. 3) CURRENTLY HAVING AN ISSUE WITH THE "CHECK ENGINE LIGHT" COMING ON. THE CODE SAYS THAT IT IS A EMISSION ISSUE. WITH THE COMPUTER CODE READER I AM ABLE TO CANCEL THE CODE AND IT STAYS OFF FOR A WHILE BUT COMES BACK ON DAYS LATER. THE CODE IS A LEAKING GAS CAP BUT I CAN DETECT NO LEAKS AND HAVE CHANGED OUT THE CAP WITH AN OEM CAP WITH SAME RESULTS. TRUCK RUNS OKAY SO I HAVE NOT DUG ANY DEEPER ON THIS AND IT IS STILL OCCURRING. 4) WHILE UNDER THE TRUCK FIXING THE BRAKE LINE ISSUE I DISCOVERED THAT THE DRIVE SHAFT WAS COMPLETELY COVERED WITH RUST. IT WAS NEVER PAINTED FROM THE FACTORY. I HAD TO REMOVE IT TO KILL THE RUST AND PAINT IT WITH A GOOD COAT OF BLACK HEAT PROOF PAINT. CORROSION SEEMS TO BE AN ISSUE WITH THESE NISSAN VEHICLES.

FUEL GAUGE DOES NOT REGISTER PROPERLY. I HAVE ALREADY REPLACED THE FUEL CAP ONCE AND HAD THE TRUCK IN FOR REPAIRS A COUPLE OF TIMES. THE SERVICE ENGINE SOON LIGHT IS ON ALMOST CONSTANTLY AND WHEN THE FUEL GETS DOWN TO 1/4-1/8 OF A TANK, THE GAUGE WILL GO UP TO 3/4 A TANK INDICATING THAT THERE IS MORE GAS THERE THAN THERE ACTUALLY IS. IF I DO NOT KEEP TRACK OF IT, I CAN EASILY RUN OUT OF GAS. *TR
