2003 Chevrolet Avalanche 1500 Question: Can fuel from certain gas stations cause a engine light to come on ?
i guess anything is possible. yes gas could be water down.try a higher octane fuel like 89 instead of 87 that might help - globalhelper
yes and if you dont get a good seal on your gas cap it will do the same - BIGDOG9791
Yes, bought Cheap gas several times . After awhile smelled like sulfer, rotten eggs, light came on. Filled tank with high octane gas twice light went off. Did not use that gas again and had no problems. - Franksbakery
