o2 senor ?

[firebirdnta]

I got a code reading faulty o2 senor for the one on the exshust but it runs fine. Will it hurt to drive it this way?

Which O2 sensor is the code for? Is it for the one behind the cat or the one in the Rear manifold?

The One in the rear manifold is for fueling, the one behind the cat is a sniffer to make sure the cat is up to snuff..

If you need to replace the O2 in the rear manifold I will recommend AC Delco first and foremost.. Steer clear of the Bosch O2's on the Gm 3800..
