My 1989 Buick Regal 3.1 Wont Speed Up When Driving
I have changed the fuel pump and filter a couple months back and it ran fine, now its missing real bad so I changed plugs and wires and air filter and put fuel injector cleaner in it, and now it hits a certain speed and either drops and goes real slow, and when going up hill it barely goes.What could be wrong now.

If your car has an overdrive (OD) setting, do not use it. Keep it in drive and that may help. My Chevy Lumina did the same thing on hills. Your overdrive may be on the way out. Keeping it out of overdrive won't fix it, but it will buy you some time. If the overdrive is defective, that usually means your tranny is nearing the end of the line and will need to be rebuilt soon.
My other guess is a dirty throttle body. Spray carb cleaner into the throttle body while the car is running. Have a friend rev up the engine so it doesn't stall when you spray the cleaner. Be sure to spray it at arm's length, in case of a backfire. Carb cleaner is very flammable, so use it with care.
