After washing my 825i I lifted the bed to spray off the engine. Left it to dry and when I went to drive it again the engine ran rough and had little power. Has been that way since. I changed the fuel and checked all connections, etc. but found no obvious defects. Did I fry something? Key was off during the water contact and wasn't turned back on until hours later when I went to drive it again. It has low hours and hasn't been "worked" hard at all. It almost seems to be running on only two cylinders.
