[mecheddie@mac.c]

Dear friends,
I bought a 1995 E320.Eng. was running fine untill I wash down the Eng.with the gunk.Soon after the Engine started missing,so I check all the spark plug hole for waterand there it is full of water.So I dried them up,but still mis.I know for sure that the #3 cyl not firing all the time and The Eng. would not rev up pas 4200 rpm.I put all new spark plugs and replace all ignition wires and boots.Its been seating for Three weeks now and everything should be dry by now.
Any body run in to this kind of problem before?Thank you for your respond.
