Shout out to manager John K and Nick. My check engine light came on so I drove to AutoZone where the manager lent me the analyzer and it came up bad ignition coil. I was able to fix my car on the spot with some pointers from John and Nick (and YouTube videos). So far, so good. My car is running much better. Saved me over $$$ doing it myself rather than paying a mechanic to do it. Ladies make sure you watch those YouTube videos before attempting anything yourself. And ask a qualified mechanic friend for pointers. AutoZone employees can't do the work for you but they can give you some suggestions. John K is a really good manager - consider him for a district manager! read more
