Yesterday evening I washed my engine bay at the body shop where I work part time. I used orange power degreaser, and a pressure washer, but stood far enough away not to wreck anything. When I pulled the car in, it was idling around the usual 800-900 rpm, but when I pulled it out, it was idling between 2000-2100 rpm. After letting sit for the day I tried it again, but it did the same thing. Any ideas as to why its idling so high?

You probably knocked loose or broke one of the small vacuum lines. A vacuum leak will often upset the idle speed and quality.
