Chevrolet Impala Problem Report
Chevrolet Impala Check Engine Light and/or Lack of Power Due ot Flex Fuel Calibration Error
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've recently had this issue! My car would not go over 25 mph over the interstate due to loss of engine power. The dealer had it over a week and couldn't find a problem. They suggested it was the E85 I had started using. STAY AWAY FROM E85! - Visitor
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. - Visitor

I filled only half tank with E85 but my fuel gage started to read full after I drove more on it but when I started my car back up it read low fuel then I was on my way to the had station and it began to rise all the way back up to full and I put more E85 to be safe but the next day after driving around my check engine light popped on then the low fuel light then my car turned off from having no gas. - Visitor

FOR EXAMPLE: I just filled up the tank-my gauge indicates maybe 1/4 tank-I drive 2 miles-gauge indicates maybe 3/4 tank-next day when I start the car, gauge indicates maybe "empty"-I drive 5 miles,...
fuel gauge does not register right
