Why would there be gasoline in the intake of my 3100sfi lumina 1998?

Ok.. Basicaly it sounds like the gas which should be vaporised is pooling in the intake. Its likely getting in because its not getting burned. I have seen this with both fuel and oil. The smog equipment on the car recirculates a percentage of exhause and crankcase vapors. Unless those misfires are caused by a bad spark plug or wire this will not be a cheap fix.
