engine problems on 1992 Buick Roadmaster

what does it mean when the engine jerks when i go over 45

Asked by for the 1992 Buick Roadmaster
Could mean an engine misfire, transmission issue or possibly something else entirely. These types of problems require experiencing the problem to better understand what is happening. I suggest you find a mechanic and have them go for a test drive, see what they say.
Just fixed that problem. After changing plugs and wires it turned out to be the distributer behind the water pump.
