Threw a CEL for EVAP Emissions. WTF is that?

 

yea same here it a whole system designed to filter or gas fumes and to detect leaks in the fuel system

 

What are we suppose to do about it? It only threw the code once after it detected I was running lean at idle due to my intake, but never poped up again

 

On a lot of cars you'll get an indicator light if your gas cap isn't screwed on tight enough. I'd check your gas cap, and if it doesn't come back it's probably no big deal. If it does come back though, it means gas is evaporating OUT of the fuel system (leaking out of the car and into the atmosphere). If it comes back, just take it to the dealer
