Question about O2 sensors
Question about O2 sensors I installed my headers & off road y recently and unplugged the O2 sensors for now. I am getting the car tuned & O2 deleted. In the meantime, will these codes cause any problems?

IMHO,
when your tuning using a tool like LS1edit your NOT turning the functions off, your just preventing the PCM from tripping the error codes to be stored or turning on/off SES light.
The rear O2s have more function then claimed for they also play a part on cold start to determine overall what the injector pulse width will be for that drive cycle.

I am not going to run O2 sims. Do I have any worries between now and the time I have the codes shut off?

like horist said as long as the fronts are connected and reading you'll be ok, just will have an SES light over it.
if the car is being tuned just have the rear 02's deleted from the tuning. will be the only way to do it really if you aren't going to run sims.
