Hi, My name is***** will be helping to answer your questions today. Is your car E85 compatible? Do you get any check engine codes?

Customer: replied 8 months ago.
It did not show any code until recently it came on when trying to accelerate through rough running. It stayed on but have not had it checked.

What about the E85? Is your car rated to use the E85?

Expert:  Jaybird61 replied 8 months ago.

Your engine may not be rated to use E85 gasahol and when you use it and then go back to regular fuel your computer is having problems adjusting to change. When your running regular fuel what is your engine doing? Misfiring? Engine Pinging or spark knock?
