I have a 99' but im assuming the codes are relatively similar throughout the years. My service engine light came on and when I ran it I got the P0440 - EVAP system leak code. I believe that is code 0705 for those unfamiliar. According to the stickies it could be a bunch of things but I was just curious if a leak in the exhaust could be the culprit here, or does the exhaust play no role in this.

 

exhaust plays no role in this, its a vacuum leak of some sort or maybe one of the evaps are going bad
