O2 sensors tuned out...consequences?
apparently one of my 02s was out and they were just tuned out while i bought new ones, now its winter and im wondering if anything negative can happen by me still running that tune.
If front, the ECM has no idea what the A/F ratio is. Get them reactivated!
If rear, they only tell the ECM whether or not the converters are doing the job right. Not a big deal.
So if you have issue/problem at WOT, turning on the front 02 sensors won't fix it.
