02 sensors

[00CericaRuss]

I've got a POS autometer a/f ratio gauge, and had it hooked up to one of the o2 sensors by the inside fusebox, it was really bouncy... someone told me about the other wire down there that goes to a 02 sensor further back...

anyone know which is the better of the 2 o2 sensors to use for this gauge?

It seems alot less bouncy now on the rear sensor, and for all I know, it's more accurate.

Anyone got any insight on this?

It's like this because of the feedback circuit. For any hope of good reading you will need to install a third O2 sensor before the cat.

Here's copy of the service manual.

thanks for the post victor, but what i'm wondering, is why does it seem to give better readings under normal driving conditions?
