Emmissions problem. HAVE THE ENGINE CHECKED!

Emissions
No pure ethanol produces no CO2 Emmissions but they will produce NOx emmissions
It is on because there is a problem with the emissions system. Have the ECU scanned with an OBD2 scan tool. The code it retrieves will tell you where to start looking for the problem.
There are multiple cleaners you can purchase in autoparts store. I recommend Seafoam. The only problem is that you will have to change oil soon after adding Seafoam in the tank. So plan cleaning accordingly.

I am having the same problem and found that there was a leak in my exaust system. I fixed it and it stopped the backfire. I also heard if you seafoam the gas that it could help. The air idle screw on your carb acts like it does nothing but if you adjust that it can also help reduce the bacfire but not stop it.
