Hello my name Roger Holmes and my bonneville is misfiring. What happen was I washing the engine and the battery die and I call the tow truck for a jump. One of the spark plug must of gotten wet (i don't know that what the tow truck guy said) then the engine back fire sound like a gun shot. The pressure sensor (or MAP sensor) pop off broken half then there was a crack on the intake housing that I fill in with sealent but with the pressure sensor replaced and the crack taken care of it still misfiring and will not stay running what do I do next
have the same problem?

I think I would still be concerned about the crack.
You'll probably need a new intake manifold for a start.
I think it might be a good idea to do a compression test. Post the results.
