Have a problem when driving in the rain. Engine will cut out, like serious misfire. Will keep running smooth and then cut out. Have inspected air filter and found saturated with water. Replace filter and runs good until filter gets wet. How to keep air cleaner dry. Have added 3inch pipe and moved intake opening higher up toward hood. Helped but still happens in hard rain. Any ideas?
The bulletin in the link shows the "shield" which was Ford's first attempt at fixing the problem. If you don't have the shield the bottom section of the air inlet tube probably is the original right angle (rather than straight down) tube with the opening facing the front of the coach. The reason the bulletin says "some" chassis may experience the problem is because the body builder determines the shape of the grille and where it is in relation to the air inlet tube. This in turn determines whether the inlet is shielded or is or exposed for possible water intrusion.
Our 2001 Adventurer never had the problem. However every time I took it to the Ford garage for service they recommended I do the upgrade. I finally relented and had them do it. The cost at that time was only $12.00. As time went on it got more and more expensive. The last person I knew that had it done paid $80.00 for parts and labor.
Since the bulletin applies to 10 - 15 year old motorhomes you may have a problem trying to locate a kit.
Thanks for input. Have modified air intake so it is above grill opening, but still has problem. You have given me ideas. Will post if I solve it.Thanks again
