Crazy code readings
The check engine light came on in my 2007 GMC
Yukon XL. I took it to the shop to see what was up.
It came back with 23 things that were supposedly
wrong with it but I am not having problems with any
of the things that the computer is saying are broken
or malfunctioning. Anyone ever have this problem
or something similar?! Not sure what to do.
