Used 17 GS - poor fuel economy
Is there a fuse pull trick to reset the ECU on a 2017 Grand Sport Automatic, like pulling #5 and #20 on the Gen 5 Camaro?
If so, which fuse(s) or just disconnect the Battery?
Not sure if regular gas was used for the 'complimentary' fill up upon vehicle purchase from a (non GM) dealer, causing such poor fuel economy, but i'm getting only 9.7 mpg in mixed highway/city driving.
Or should I be looking for other problems (beside PbPeditis)?
