My 92 300CE is affected negatively by moisture. After a hard rain, it may be difficult or impossible to start, and then after starting -- if there has been a recent rain, it may start to run rough and then stall after reaching normal operating temps.

What connections or unit can cause these failures, which are linked to wet conditions only?

Thanks for any ideas or solutions. Ben Carter
