Picked up a '95 GT. Wasn't running right when I bought it, but..... Anyway, I unplugged the battery for a few days, it ran excellent, for five minutes. Then it ran like ****. I replaced plugs, wires, cap, rotor. Went with Autolite copper instead of platinum reading a different thread. Back to this problem. The last few times I fired it up, it would idle, but when I stabbed the trrottle it would begin backfiring and not revving. In fact, I floored it (all of this in Park) and it just died. Now it won't idle for more than a mimute or two, before stopping. I am unplugging the battery between startups, and I am only starting it in the morning and afternoon. I have some injector cleaner in the tank that I want to get to the injectors. Thanks.
remove and clean the iac also check the timing and firing order,if this checks out check the coil.stop disconnecting the battery unless you have a reason for doing this.
I disconnect the battery because I am still working on it in between. I have the water pump out for replacement, I am putting on a new harmonic balancer, and while I am in there, I am putting on a set of under drive pulleys. The firing order is fine, what is the timing supposed to be? Car is mostly bone stock. Did the 94 GT come with factory headers? Otherwise that is the only mod I am aware of. The thing idled fine two days ago after the tune-up. It just wouldn't rev. Now it stalls when idling. I read on another site that disconnecting the pos off the battery could cause the computer to "blow". I have been disconnecting the pos. Thanks
