1997 Honda Passport

LEFT HOUSE AND PROCEEDED DOWNHILL ON GRAVEL DRIVEWAY AND THEN TURNED LEFT ONTO MAIN ROAD WHICH IS A HILL RISING APPROXIMATELY 200 FEET OVER .5 MILES. AT TOP OF HILL LET OFF ACCELERATOR BUT THE SPEED WAS STILL INCREASING. TAPPED ACCELERATOR, PULLED FLOOR MAT AWAY FROM GAS/BREAK PEDDLE AREA, TAPPED ACCELERATOR, WHOLE TIME DEPRESSING BREAK WITH BOTH FEET. FINALLY CUT OFF IGNITION AT APPROXIMATELY 55 MILES PER HOUR. I COASTED THE CAR BACKWARDS WITH ENGINE OFF AND TURNED IT AROUND. WHEN I RESTARTED CAR THE ENGINE WAS AT IDLE AND I DROVE IT HOME WITHOUT DEPRESSING ACCELERATOR. WHEN I CHECKED CAR AT HOME I OBSERVED THAT THE RUBBER THIMBLE COVERING THROTTLE CABLE AT THROTTLE WAS DETERIORATED. I PULLED THE RUBBER THIMBLE OFF AND OBSERVED THAT THE RUBBER HAD ENTERED THE THROTTLE CABLE HOUSING AND WAS THE CAUSE, JAMMING THE CABLE AT THE ACCELERATED SPEED. I CLEARED THE CABLE AND HOUSING OF THE EMBEDDED RUBBER AND CAR ACCELERATED/DECELERATED NORMALLY. A PRECURSOR TO THIS WAS THAT MY GAS MILEAGE HAD DECREASED DRAMATICALLY ON THE LAST FILL UP, SATURDAY, FROM 19MPG TO LESS THAN 12MPG. I WAS LOOKING FOR A LEAK AND HAD INTENTIONS OF BRINGING IT INTO THE REPAIR SHOP ON MONDAY (TOMORROW). *TR
