Flex fuel vehicles can develop fuel calibration issues resulting in illumination of the Check Engine Light and/or lack of power. This commonly occurs if only short trips are taken after changing fuel type from E85 to gasoline or gasoline to E85. In most cases, the fuel calibrations can be reset for gasoline using a properly equipped scan tool.

    My car would actually cut off while on the highway. I would have to pull over and wait about a minute and then restart it. I thought it needed a tune up so I got that done and the mechanic told me about some sensors, the accelerator petal, fuel injectors etc. and he fixed it. I have not had THAT problem since.
