Start with a good tune up, new plugs, wires, dist cap and rotor, fuel and air filter. Clean the idle air control and inside the throtle body, and run some injector cleaner through it.
water in the fuel can cause an idling motor to sputter and/or die.
Could be in need of a tune up.

Possibly. The main thing it can cause is severe engine wear. Too much oil is just as bad as too little.
Could be EGR valve sticking open or dirty at an idling condition or hesitates when accelerating.
Have it checked for codes, and diagnose the code.
If the check engine light comes on it is best to take it to a auto part store or mechanic for a diagnosis. They will be able to inform the owner what the issues is.
I have an 04 Venture that did the same thing. Turned out to be the Engine mounts, apparently it is really common. Since i have gotten them replaced i haven't heard the noise or had a single problem.
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.
Replace the Idle Air Control Valve only about $50. This would cause funny idling and stalling out.
It could be many things. Try spraying brake cleaner on the back side of the engine where the intake manifold meets the cylinder head. If the gasket is bad the engine will mis fire or stumble.
A car that is stopped with the engine running.
