For some reason, my scanner is not allowing me to reset fuel trims anymore.... I have been able to in the past, but it is all grayed out now. And yes, it is "connected". All other functions except for my fuel options are working properly.
I have the same problem but from day one. I guessed that it was unavailabe but who knows maybe it is a bug.
2003 Cavalier 2.2 L4. Modified Intake and throttle body. Header and 2000 watts of boost in the trunk.
