bucking gtp

i have a 2000 gtp and about 2 weeks ago it started bucking and jerking when i reach 45 to 55 mph. any ideas????
 


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?
 
a lot of miles 250,000 we changed the fuel pump and it ran fine for two days then started again. it mostly happens when i go up hill.
 
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.
