Michael,
I'm trying to envision in my head the systems you could have affected by
spraying the underside of your bus. If the engine splash shields are in
place, then I can only think of fuel lines, fuel pump with connectors, and
ground straps. I don't know where the charcoal canister/fuel vapor recovery
vacuum lines are on your model of bus, but I'd check that too. Those would
be the items I'd check first. Id start by lying down under the bus and
slowly looking at EVERYTHING.
It could also be a mere coincidence. Did you fill up with fuel just before
the wash? Bad gas? What if water got into the fuel system? A cheap
bottle of fuel dryer would answer that question.
