Why does nobody talk about how bad injectors fail in the rain...

Last Tuesday I was on a job outside Lafayette, working on a 2015 Freightliner Cascadia. It started raining halfway through and the truck went from running rough to dead in the water real quick. Pulled the valve cover and found water creeping into the number 4 injector wiring harness, corrosion had built up over time. I dried it out with compressed air and replaced the harness connector, fires right back up. Anyone else run into moisture getting into their injector plugs like that?

I had a 2014 do the same thing in Mississippi fog last spring.

Mississippi fog is a whole different beast, it just hangs on the ground and doesn't lift.

Yeah I actually read a review somewhere that said the 2014s had some sensor issues in thick fog, something with the adaptive cruise control freaking out. I guess the fog just messes with the calibration on those models more than others. Makes me glad my old truck doesn't have all that fancy stuff.
