Answer
Sputtering is usually ignition related.

You put water on the motor? Were you trying to wash the engine?

If so, the plug wires are wet and arcing to the block. The more you drive the car, the better it will get. Will take a week to dry out.

Don't wash your engine. Use a damp cloth or engine cleaner.
