I guess your trac and check engine code is on also? Replace the sub 02 sensors. Or tie them into the other two. That's what I did. The lights cleared and my throttle response was back. Just my. 02.

Just be careful on replacing parts that are still good. A CEL from an 02 can be caused by a few different things and not necessarily the 02 Sensor itself.
