Hello Sir,
I have just created an account here based on your experience with the VXDiag and reseting the Alcohol Fuel Percentage. I have an 2009 HHR ( I know its not a truck ;)) but it is a flex fuel GM with the same problem you have experienced and I am needing some guidance if possible... I have purchased a VXDiag GM and I have install the tech2win software and can get into it and connect with my vehicle but for the life of me I cannot find the Fuel Composition Reset Function? I have searched youtube and the inter webs for HHR specific forums and I come up short for finding screen shots and menu layouts to find this function... Could you please lend me hand? Maybe hookup to yours in your driveway and take some screen shots? Or just text menu path... thanks,
