I used to think you had to go to a mechanic for everything, but a guy at AutoZone changed my mind
My check engine light came on last Tuesday and I was ready to drop $150 at the shop just for a diagnosis. Then this older dude in the parking lot at AutoZone on Broadway asked if I'd checked the gas cap first. I laughed but sure enough, it was loose and the light went off after a few drives. He also showed me how to use their free code reader for next time. Now I wonder how many simple fixes I've paid for that I could have done myself. Has anyone else saved money by just asking someone at a parts store before calling a mechanic?
