Is anyone having problems with this stuff. Any codes goin off. Mine is code 171 which is Bank 1 sensor 1 is Lean. I dont know what else to do. I just posted previously on same subject. Help

I run gas with ethanol all the time. I don't even know if you can buy it without around here. No problems with afr though. Maybe the tune isn't fully sorted out or a bad 02 sensor? If one bank is lean the other should be as well. Or possibly you have an air leak on that side.

Both of my front O2's are new and been changed. What do I check for? What kind of leaks?

I have run 100% E85 for many years without any problems.

Check for a header leak either at the collector or the head. If it's leaking then it's also sucking air and the 02 will think it's lean.
