I got a p2096 code on my 2005 jeep wrangler sport 4.0. I’m not sure if it’s the fuel injectors, but I have about 110,000 miles on it anyways and wanted to change the fuel injectors. I’ve looked online and I couldn’t get a definite answer on what fuel injectors I need does anyone know which ones I need or where to look to find the answer ?
Which fuel injectors do I need?

Have you actually pulled and tested one? Why buy something you might not need?
I'd start with the O2 Sensors.

Watch out for the recommendations to go 4-hole injectors. They seem to be a 'seat of the pants' upgrade that the computer quickly removes. That's been what I've surmised from the community anyway.
Just do your research on that when someone inevitably tells that's the answer....

I have replaced my downstream bank 1 02 sensor. I used ngk for the brand. My check engine light went away for about 150 miles and came back. My fuel injectors seem to be working fine, but my mpg has gotten a little worse so I figured I can replace my fuel injectors
A 2096 is more likely to be an exhaust leak or bad O2 sensor than injectors. Do you have a misfire?
This.
For an injector to fail at a little over 100K is rare. I'd replace your other O2 sensors and see what happens.
As to the injector type. I'd match what's in there. Don't buy into the more holes the better performance stuff. Not with this engine.
Just take the injectors to a injector shop and have them cleaned and flow tested, but replace all the o2 sensors before that. Your 05 has 4 hole injectors stock I believe.
Yeah I’ve only changed the bottom front 02 sensor. Should I have changed both bottom and top bank 1 02 sensors ?
You need to replace the top 2 O2 sensors as they are the ones that control the mixture. The bottom O2s are mainly to monitor the cat efficiency.
If you replace the injectors, you can go back with stock 1 holes, or pick up a refurbished set of Bosch 4, or 12 holes. The ones with more holes have a better spray pattern, that is the only benefit. You aren't going to see any big improvement from them over a clean stock injector though.

I had a similar issue and sent them out. Then I put in new filter baskets and top and bottom O rings. Ran better.
Usually the claims that 4 hole are better is because they are replacing old clogged up single hole injectors.
Both new, you won't notice side by side.

Make sure to only install NTK, NGK, or Mopar O2 sensors... with the latter two made by NTK.
Did you ever replace the remaining 02 sensors? If so, did it resolve cel problem. I have had this same issue for some time. I also replaced the one sensor and ran code free for a while, but now it comes back within 50 miles or so. P2096. Thanks
There is a TSB on that code for a ECM Reflash

I used NTK, NGK . Jeep runs fine, just get CEL.
