I looked under my hood when i got home from work this morning when I knew something didn't sound right,and saw that my drive belt has about had it and its a cheap one that I bought and its just 3 months old and I drive 45 miles 1 way to work everyday. My check engine light has been coming on,i'm wondering if my drive belt was causing it,and if it was,a new belt should fix that problem. This time,i'm buying the best belt in autozone.
