Car's sputtering after my wife drove it through a street w/ alot of water on it on 2001 Chevrolet Prizm

Ever since my wife drove her car down our street during a storm, her motor sputters upon accelleration, and shakes when idle. Changed spark plugs & still no luck. Any ideas?

Yes, there is still some water, most likely on or near the plug wires.
