I have a 1997 Chev Cavilier 4 cylinder. Both the upstream and the downstream oxygen sensors need replaced as well as the air intake sensor. When I am driving, the car will all of a sudden burn about a quarter tank of gas in an instant, and there is a smell inside the car. Does this have something to do with the oxygen sensors?
