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.
No it will not cause misfire.
Contaminated fuel could cause a misfire.
old fuel filter
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.
Cause it does
There are several reasons that can cause your 1995 Buick Century to quit running. The most common reason is a lack of fuel. A bad fuel pump can cause the engine to quit running.
