I bought the car used from a side shop dealer, 104,000 miles on it. Just that one problem.

More than likely you have an engine misfire. When you first start out a cold engine requires more spark(and more fuel). Also dampness can affect ignition wires and coils by reducing the resistance in the wires. As you drive the engine heat evaporates the dampness. Coil replacement is commonplace as well as the wires. Pull the spark plug boots and look for black streaks along the spark plug insulator. These are carbon tracks that the spark can travel along rather than jumping the gap on the spark plug tip. If you see them replace wires and plugs. Also check your transmission fluid level. Best to check trans levels after the transmission has been heated up but it should at least show on the dipstick when cold. There are other possible things that can cause your concern but I think these are a good starting point.

I would first have the throttle body cleaned and then drive it a week or two and if this did not cure it I'd get a "tune up" whcih means new spark plugs.
Most people push these new cars to 100K miles without a tune up and this is not smart. The engine timeing is based on the #1 cylinder and if all of the plugs have a different gap in them then the timng is slightly different in each of the cylinders. The gaps in the plugs are probably way too much if no on has done a tune up on it in the last 50K miles or more.
Good luck!

Because it is a 99 Buick Century... what did you expect when you bought it? It's hardly a luxury car..

Because:
1) It needs a tune-up
2) There's a problem with the transmission
3) It needs a tune-up

Maybe the transmission is slipping with miles that high. And the trainey can cause it to jerk.

Because your mom's head keeps hitting the steering wheel.
