I have a 2010 Chevrolet Traverse 3.6L and the code is p2178. How can I fix it? Thanks!
HI there
Basically, this code means the fuel system is too rich during acceleration, or during cruising speeds. This can be the result of a faulty mass air flow sensor or a problem with the fuel pressure being too high. Here is some more info.
