Need help figuring out "lazy" O2 situation
My O2 sensors have been replaced but i'm getting codes. Watching a datalog of both front sensors the bank 1 sensor will suddemly go rich (freak out) I have a wideband and can see that it's a false reading. Also verified at the tuners shop with his wideband. I have to renew my Emissions tes on the 25th and need to take care of this being it's got the MIL on. Any Ideas? Thanks in advance?
