Oxygen Sensors

[casm]

A few months ago I replaced the oxygen sensors in my 2000 Limited. At this point, I suspect they may be blown again given the craptastic (13-14mpg average) mileage I've been getting over the past few weeks. My suspicion is that I screwed up when I ordered them and got the California-spec sensors out of habit; mine is a 49-state vehicle.

Assuming they are shot (symptoms are the same as before I replaced them), what are the correct Bosch part numbers for the upstream and downstreams sensors on a 2000 model-year 49-state vehicle with the 4.0? If it helps, this one does not have the cats on the downpipe.

don't you also have a secondary O2 sensor behind the cat ?

The down stream sensor does not effect mileage it only checks the CAT. Where where you when you bought the sensors?
Upstream Item#: BSA13100 Downstream BSA
13138 Napa.

Uh, I did do both at the same time - hence why I kept referring to them as sensors

In California. Really, I think I just brain-farted, forgot it was a 49-State vehicle, and ordered the CA-spec sensors out of habit.

Hmm, what about a sensor # for a '94 jeep? But only if ya guys have it on hand.

don't know the part numbers, but i was at napa last week, and if you buy a bosch o2 sensor they give you a $10 gas card. don't know if they still have that deal though.

Send some decent blueberry latkes my way and we'll forgive you

At Autozone here in TN. the part number for your O-2 is 13100 at $63.99.
This is for the Bosch OE sensor.
Both sensors have the same part number.

Hope this helps
