Where I live, we have both gas and etanol.
Sonic accept both fuels, and has a sensor to detect the porcentage of ethanol on it.
It happened not once, but twice times, when I filled my thank with etanol only, that the sensor locked in "etanol" and after that, when back to gasoline, I had a hard time trying to start up the engine.
So I had to take it at the GM service, and they used the scanner to reset the fuel type/porcentage information from the memory.
Can I perform this at home? Can I do it with a cheap OSD reader/iphone app? Can I reset it just by uplugging the ECM fuse?
