First of all thanks for reading my post/issue. I have a 2000 7.3 with 200k on it. I just have the in line fuel pump go out and changed it and this issue has popped up again while cleaning off fuel spillage. Any time I wash/clean the engine bay or if I go through heavy rain it will start running rough. I loss power and the EGTs will skyrocket from normal IE from 650-700 to 1000-1100. I have changed the cam sensor,and exhaust sensor. Any help would be .............well helpful.

Pull your IDM and look at the back plate for water damage(rust) -- had a guy a few days back that had a hole rusted thru
The engine harness is likey old -- some of the insulation would either turn to goo or get brittle and flake off -- possible if the IDM is OK, then you may need to check the harness closely

Thanks For the response Hydro. I am going to dig into it today hopefully.
