    Are you trying to maintain the 45-55mph or is it a WOT pull? How many miles? Recent work done? When was the last time it had a tune-up? Is the CEL on?

    On a side note, where did you find a hill in Florida? (save for near Alabama)

    How much throttle are you giving the car when it's bucking???

    Pull all the plugs and check their condition. When I bought my GTP in January, I had the same issue. Number 2 plug was spider cracked and causing a nasty bucking.
