I,VE HAD ENG.LIGHT COME ON & STAY ON & EACH TIME I HAD TO REPLACE THE GAS CAP. THIS WOULD SOLVE THE PROBLEM BUT THEN AT DIFFERENT MILEAGES, THE ENG. LITE WOULD COME ON AGAIN THIS HAS HAPPENED 4 TIMES IN 140,000 MILES. NOW I,M TOLD TO INSTALL A NEW GAS FILLER TUBE.
i replaced it with the recomended revised parts, in 6000miles or so its started doing it again..
