Cars bucking...

Welp... I washed my engine today, and stupidly think I got something wet. I've washed it twice before and just made sure I wasnt directly hitting the dist cap and 'Kiss Me''Kiss Me''Kiss Me''Kiss Me', but I guess this time I may of gotten something wet, because I washed it then drove around and everything was fine. Few hours later me and a friend go out, and no when I'm cruising and it drops to about 1800 RPMs and I take off the car will buck really bad. What do you guys think I focked up? And will it dry up and stop or am I looking at replacing it?

Thanks for the reply man. I took it into auto today and once I took off the rubber boots or whatever that go over the plugs, some were wet and nasty looking. Lets just say my spark plugs were pretty bad. They were pretty nasty, and my auto teacher said there were three different kinds of spark plugs in my car... weird... runs pretty good now.
