Hey guys im new here i just got a 2005 mustang Gt its the redfire colorits got lowering springs, hurst shifter, JBA headers , CAI, drilled and slotted rotors. Ill try to post pics
I have been curious if the stang is runing lean or not because the back 2 O2 sensors are "stuck lean" im wondering if it has to do with the exhaust setup or if it is actually lean. Is there another way to tell what the A/F is?
If your car isn't throwing a lean condition code, you should be good. But I'm not familiar with the newer stangs, so you could start a new thread in the Tech section. They'll know more.
Runing lean?
