- 2017 Ford Explorer Sport
I tried to reflash my 2017 explorer sport ecoboost 3.5l back to stock and all kinds of check engine lights came on with traction control and hill assist. When I started, it surged forward like it was in gear. So, I figured I'd refresh back to the AO auto octane tune and everything is back to normal. I'm concerned because I live in California and can't smog it with a tune on. Can anyone give feedback on what to do. Thanks guy's
