Engine won't rev over 2,000rpm

This morning I got some engine degreaser and cleaned the entire engine.
I covered the distributer,and the coil (thats all).
After I was done, I started it up, and drove out of my drive way. But as soon
as the tach goes over 2,000 the engine dies untill it's below 2,000. (It won't stall
but it will cut off the gas untill im under 2,000 rpm). So i have to shift at 2,000 rpm,
which isn't fun. Please help me. The only thing i can think of, is that water leaked
into electrical somewhere, and screwed it up. Maybe I can just wait a couple
Hours and it will cure it's self. (and the water will evaporate.
thanks for any advice.

even when i put it in neutral, i can completely floor the pedal and it will rev up to
2,000 then go back down in the 1's.
