Much to my dismay, I found out that autozones near me are no longer checking check engine lights for free anymore (or for the last three years as some of them told me) and i was wondering if there were any other resources I could go to before having to bring out my wallet. I have gt1 and everything installed but am not familiar with it to the point that I know how to get the check engine light code from it (although I think I have once but I just didn't know what to do with it) any help?
