You can check the battery connector. Make sure they are not corroded; and see if there isn't any melting on it; sometimes it will startup but drive rough, make sure the the connection is tight. Also I think platinum spark plugs come standard on some Buicks, which have a very small electrode and a little gunk will cause them to misfire; I would swapped them for a set of old champion copper plus spark plugs and a new set of spark plug wires.
Yes, that is one of many possibilities.
Moisture will be the cause for an engine misfire. Depending on the year of the car will have a bearing on the solution. It could be that the plug wires are misfiring due to dampness.
005 gap is pretty minimal. While the engine may not run perfect and fuel economy may be affected, it is not enof of a difference to cause sputter and misfire. A .005 gap difference in what we need to know.
I have a 95, had a misfire... mine was because of the plug wires... changed the wires and plugs mis fire stopped...
It can be anything from the printed circuit in the dash to the speed sensor on the trans. Have it checked out by a good mechanic.

Contaminated fuel could cause a misfire.
old fuel filter
Water can get in and cause a misfire.Water can get in and cause a misfire.
A malfunctioning battery can't provide enough power to your ignition system when the motor is idling can cause sputtering. If there is not enough gas, that can cause your vehicle to sputter. If the spark plugs fail to fire will also cause your vehicle to sputter.

i have a 1996 buick century just came back from mechanic head gasket is gone and there is anti freeze in my oil i guess if you had water in your rad then you would have water in your oil.
mabye the O2 sensors
a tune up will fix that If plugs and wires do not fix you may want coil tested if still not fixed look at injector
An intermittent crankshaft sensor will not let the engine fire the correct times. This can definitely cause a misfire for the engine.
