O2 sims
O2 sims I put headers on my car a couple months ago and put O2 sims in place of my rear O2s i was wondering if i need to keep them on for my car to run properly or just so my computer won't throw codes
Ya that's what I was thinking too. I turned off the SES code for the rear O2's to never come but I didn't think that the rear O2's did anything except read the temp or somethin like that of the rear O2's
Ya same here. Cuz I have the sims on my car sold I just haven't takin them off to ship them yet (sold them two days ago and go to work when it's dark and get home when it's dark, working outta state). I got to thinking after I had them sold to someone who already gave me if I actually needed them or not

all rear o2's do is detect a malfunctioning cat. front o2's will affect performance, rears dont affect performance
