Jan Gorson Mojave Desert, California - 1994 Toyota Camry
engine...parked in a wash, got flooded, water up to wheelwells. He cleaned the engine, and now when he starts the motor, air gets sucked in through the muffler and blown out through intake,like a reverse engine. While working on engine, timing belt got thrown off--by 90, maybe 180 degrees. Take it off, and put it back on correctly, problem will go away.
