Just bought a 2000 Trans Am WS6. It had several issues when I bought it. It had a bad loss of power and the dash and headlights pulsated. I found the wire on the alternator plug broken so I replaced the plug, got rid of the Auto Zone alternator and replaced it with a new AC Delco which has fixed the pusating lights and I now have a constant 14 volts at the battery when it's running. The power loss is a lot better but it still falls on it's face bewtween 2 and 3000 rpm's. I replaced the original plugs and wires since it has 90k miles and it still didn't fix the miss. I'm thinking it might be the fuel pump or fuel pressure regulator. Anyone with a little insight would be greatly appreciated.
