2009 Pontiac G6 emitting an offensive odour!
 

Not sure if I have a dead animal in my AC unit or my cat is clogged, but I definitely smell a strong rotten egg smell when my car is in park, when I get out of it, and especially when I switch on my A/C and heating unit. I have no trouble accelerating, my rpms don't spike, and my engine light hasn't come on yet so I'm very unsure.
