    Hey folks, just got the transmission put in my GTP. Go to start and had issues firing it up.
    Guy told me that they may have fouled the stock plugs moving it as many times as they had to.
    I went the other night when I picked it up and threw in some autolite 104's and gapped at .52.
    Starts, runs, but very rough. Driving it home, it doesnt have any power and feels like its missing
    bad. Even with a popping sound when I got on it. I plan on changing plug wires this weekend
    when i get paid.

    But, is my gap off or something else? Its only got a FSIC, and running a 3.3 mps. Fresh gaskets
    from the lim on up. Felt like she idled and ran better on stock plugs..Idk

    Did you verify the plug wire order? These cars will run with some wires crossed.

    Plugs and gaps are fine. You probably hurt the wires moving them.
