I had the exact same symptoms one time after washing my girlfirend's 318. I did a light wash on the engine, but it turned out I got water somewhere it shouldn't have been, and that caused the misfiring. I took it to a shop where they cleaned it up for $40. I don't know where the water ended up being, but it seemed like an easy fix. Have you exposed the engine compartment to water recently?
