So I have had the LM2 for about a year now and I'm about to purchase my 3rd O2 sensor. I keep getting a E8 error message, I think it may have to do with the DFCO kicking in and the sensor going real lean when off the gas. I would like to think this was taken into consideration from innovate....But who knows, maybe it's not related but I don't know what would be causing this issue over and over. The innovate staff is no help all they want to do is sell more sensors not fix the issue. So, does anyone or has anyone had this same problem?
