I have had a heated O2 sensor in my GN since 1995 and have probably run 3 tanks of leaded race gas thru it in that time. Since I am now running an alcohol kit I have decided not to run leaded racing gas in the future for the limited amount of racing I do. Should I just go back to the stock O2 sensor since from what I have heard the heated ones don't code if there is a problem?

I believe the stock ones will perform better on the street in normal driving with regard to gas mileage, etc.

My car definately runs better with the stock single wire O2 versus a heated one. I have things wired up so I can switchover to the heated one just for track use.
