On my way back to school, I got a wiff of rotten eggs, super. I'm hoping some fuel injector cleaner will set everything straight but I doubt it's that simple. I know it can be fuel injection related or the cat, but it's not a constant smell. I smell it for maybe a minute then it fades. Does that mean anything? Or does it not matter if it's constant? Also it doesn't seem to be accelleration/driving like an ass related. Just looking for opinions of people with more experience then myself.
