Hmm,

sounds like humidity is getting through to the ignition wires to spark plugs. I would replace the wires together with dstri box or at least spread some demister in the latter.

Sorry I am not an english speaker but hope we understand each other as you look to have a lot of "mechanics experience" ( ;) ) with various ford cards

hi .i just read about your problem. it sounds to me as if theres water going into your air inlet and getting through the filter into the engine. and thats why its chugging.

hope this helps
