Can we bump this thread? I’m throwing 2 codes: P0158 (for bank 2 senor 2 02 sensor) and p0456 (small emissions leak)
So, I going to replace both upstream and downstream 02 sensors for bank 2 and decided to buy NGK’s.
Sensor 1 (Upstream) Bank 2 Part #23110
Sensor 2 (downstream) Bank 2 part #23099
Are these the correct NGK part numbers for both sensors on Bank 2?
5 minutes ago I ordered my new muffler, and exhaust. And in a few minutes I’m about to buy a Walker Cat converter that these NGK puppies will screw into. And once I’m done ordering that I will be ordering my NEW BFG ALL TERRAIN TIRES and FRANKENSTIEN RUBICON 3.5 lift.
Sounds like a lot at once and it is but my Jeep desperately needs all this and I finally have the means to do it. She needs this make over bad and I’m going to give it to her..ima give it to her real nice!!! After all this is completed I am going to work on rewiring everything under the hood. Maybe double din dash

to top her off!
First thing I’m going to install the Rubicon lift, brakes, track bar then the exhaust.. so I have a lot of work ahead of me next week when I finally start putting all these projects in motion. I have wicked bad ADD but I think that’s why I LOVE CAR MECHANICS
Talk about learning curve. I am about to
