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.
