Long story short, I bought my car used, with several aftermarket parts, including an SCT tuner preloaded. I tried today to load a different tune, got error 1034. It said if the car wouldn't start, to return to stock. I tried to return to stock, but the tuner gave error 1016. Had to have the car towed home. Any ideas why this happened, and what I can do to fix? Tried searching for both error codes on this forum, but came up with nothing.
