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.

I have been doing exactly that, was using gasoline. when gas prices spiked to 3.95 a gal i switched to E85, which is much cheaper. then had to get gas again, because I wasn't close to a station with E85. I do drive multiple shorts trips every day.
