The truck runs great on a dry summer day. When it rains and you drive it, the truck loses power and backfires. Most of the time it gets really bad and it will die out if you are not driving it or giving it gas. You could take it down the road and do about 60 mph + and it will seem fine but when you slow down or stop it backfires or misses. I have noticed my plugs look rusty but I am wondering where the water could be getting in. My brother and I have put on custom splash guards to try and keep it from getting wet. Both of my o2 sensors are shot and a clutch fan needs to be replaced. But other than that its a great truck for 276,000 miles.

Wet weather changes air quality which including your shot sensors may be enough to throw mix too lean or misture in air is effecting your ignition parts. Try treating them with ignition water repellant like wire dry.
