i washed mine and the same thing happened to me.

you most likely got water in places where it shouldnt be (ex. wires,connections/connectors, )

let the car idle it out, n after a while it should be fine.

never powerwash an engine. get a hose without a sprayer on and let the water flow around the engine after u spray engine degreaser on it. try to stay away from electrical stuff.

edit- i dont know.. if it was going from 1000 to 2000 rpm's,thats a big jump.
mine was little

Usually it gets in the spark plug valley and qenerates a sporatic idle. I would drive it as long as possible to to get it to warm up and evaporate.

Or get a compressor and air gun and start blowing off components until it fixes it.

Usually you can pull a spark plug boot and blow air in that valley and a bunch of dirt/dust/small leaves and debris that got in there will come out watch your eyes wear safety glasses.

I would also blow on the connector for the TPS and the idlle speed control and the aid flow meter. Hell disconnect em and blow the water out of there. That should solve it. I would guess the TPS could effect it the most.
