I have a 96 Cavalier 2.2 3 speed auto that has a strange problem.
Randomly when I hit 3/4 of a tank the check engine light will come on and go away at 1/2 tank or it just stays on. It also burns through fuel during this, about double the consumption. Can anyone help me, thanks.
P.S. just would like to know the problem not really interested in fixing it as this car is only a stop-gap until I get an eclipse in the next few months.
