Need some help from the mechanics on here. I have a 96 cavalier it is running rough and has a p0171 bank 1 lean code. I have checked for vacuum leaks, checked plugs and wires but doesn't act like a normal miss-fire. What should the fuel trim read? I am not sure what the injector resistance should be on this either, I know they had 2 different ones, a low impendence and a high impendence depending on year. 96 cavalier, 2.2 ohv motor, 3spd auto trans. Thanx for any help I'm kinda stumped right now
