Pressure wash engine ??
Lets face it, the c5 is notorius for getting sandy & dusty under the hood. I have pressure washed it several times with out any problems but lately, the last 2 times I must have gotten something wet that it doesnt like. It wants to misfire until it dries up. 
I just need to know where to keep away from. I dont wail on it with the pressure, I just quickly skim over the top of everything except the battery area.
Anybody ?

dont power wash it at all. eventually you'll burn out the knock sensor. its located in the space under the intake manifold and it puddles right on the sensor, so it shorts it. try a different way of washing the engine
but the miss is probably from the coils. i would avoid the fuel rail cover area.

I leave the fuel rail covers on,
cover the battery den and the aternator and pressure wash at least 2x per drive season... BUT I do it early morning on a forecast hot sunny day and leave it bake in the sun until dry before I start it...

I've never put a hose to the engine of my vette but I've read that others have and have used a leaf blower to help dry the engine compartment. My SO thinks I'm a nut for hand washing around the head covers, rails etc, but it sure looks nice when clean and shiny under the hood. A hood seal keeps a lot of dust out too.
