Replaced my crankshaft sensor and speed sensor Saturday, Thanks to AutoZone's code look-up for finding the problem for free for me! The check engine light did not go off, so out of concern I took my car up there to have the code look-up hooked back up a second time. Just needed to reset the engine and all was great! The guy was in gray and was real friendly and happy to help. Made my day. The light has no come back on since then. Problem fixed! Thank you so much!
