I have a 96 GT, and the check engine light comes on after the first quarter tank of gas is burned, then goes out till you hit the one quarter mark, and then comes back on. What the heck??????

Any help at all would be appreciated....

Thanks in advance..

Yeh what the hell my car does the same thing except it stays on the whole time after 3/4 until I refill her all the way.
