I guess I will run this tank out and switch to regular gas and then to level 2 sense it works fine with 87.Tell then Ill take it easy, lol.
The check engine light likely came on due to P0171/174 codes. These are lean codes and the PCM is unable to correct the fuel trims or has to correct more than 15-20% from base. It takes A LOT more E85 per unit of air to compare to gasoline.
