I'm experiencing a sulfur smell from under my 2010 Aveo5 after driving. It is more noticeable if I rev the engine to higher RPMs. I don't smell it while driving, but only when I stop and get out of the car.
The car is a 2010 Aveo5, 1.6L, 5 speed, 13,500 miles
I use synthetic oil.
No check engine light.
I'm pretty sure I'm not burning up the clutch because I am experienced with a manual. Also the clutch feels fine.
I recently put on a K&N air filter, but I was smelling this smell even before I put it in. I've been smelling this for probably 6000 miles, it's just getting worse as of late.
Does anyone know what is going on/ have had this problem? Online says it could be the catalytic converter but this car is so 'new' that I wouldn't expect the cat to have problems yet.
