My Rover has been a reliable daily driver up until yesterday when it started running rough and a check engine light came on. I've tried 4 different obd2 scan tools (all different brands) and each scanner is showing I have no fault codes. Anyone out there know why I have a check engine light on but the scanners show I have no fault codes? Any help would be greatly appreciated as I'm stuck with daily riding my bike (makes grocery runs a pain in the ass!).
