If you washed your engine some water may have got in to the spark plug/coil pack area. If you have a misfire code this is probably your issue. You can remove each coil pack and let them air dry for a couple of hours. When you replace them, make sure you put a dab of some dielectric grease inside each coil pack before replacing them. Let us know what you find out.
