Lately I have been getting this odd noise in my engine compartment that sounds like a really loud fan. My check engine light comes on every once in awhile. I had my fiance get the code using the computer system and it says that it is a very small leak in the evap system, and not to worry. I am going to worry because when i idle it sounds like my car is going to fall apart. Does anyone know what is really happening and what I should do to fix the problem at a minimal cost?

 

What was the code?
