O2 code and NTK sensor no longer available

[Deputy Dodge]

At the end of a day of forest road driving I shut off my 99 TJ 4L. When I restarted it I got a CEL and very rough running engine. Scanner showed a high voltage for both O2 sensors and live data showed they were both stuck at 1 volt. The Jeep is new to me and has over 200k miles. Regardless of what other wiring problems it may have, it's time for new sensors. It has been smelling rich since it bought it. So after looking at a few threads I go looking for new sensors. Nothing local. Rockauto has the NTK rear but not the front, but they do list a MOPAR upstream for $99! Ouch! Amazon says I can't have an NTK for over a month, and I'm not holding my breath on that one.
Question time: Do I order the Mopar front, or order 2 of the NTK rears and splice the connectors to fit the front?
Thoughts????

NTK23151? Or as the flaps web sites like, NTK 23151.

I see it in stock at a few local auto parts stores. Did you try napa? Probably not the cheapest, but you could have it in day. Assuming you are in Wa state.

Front and rear O2 sensors are different, you can't just change their connectors.

Go to ngksparkplugs.com. They have ignition and sensor sections to choose from. I got my plugs and 02 sensors from this site. Hope it helps anyone looking for these items.

I had to get a couple from a seller on eBay though not sure which specific part numbers they were. Seller seemed to have a good stock and selection of part numbers. If you can't find them elsewhere, worth a shot.

I can't vouch for the ones I bought yet. They look legit but my Jeep has been apart for a while and I haven't installed the new O2 sensors yet. Just got the old ones out yesterday.

Did you pull the part numbers and try local parts places?

Both available on ebay.
