That's what mechanics are for. They get to look, hear, feel, poke, and diagnose the cause. Start by having the diagnostic fault codes read. The sulfur smell is caused by a problem with the catalytic converter, and that suggests a fuel-related problem.

A defective map sensor can result in too much fuel going into the engine, but they don't fail nearly as often as they did in the late '80s and early '90s.
