KOOKS LTH - P2096 Code

[S6DIDDY]

Recently installed looks LTH, after 500 miles got a P2096 code. “ Post Catalyst Fuel Trim System Too Lean Bank 1”. I have 02 spacers installed. Any ideas on what could be throwing the code? Also the 02B1S2 voltage was reading at 0.125, where the 02B2S2 was reading at .670

Spacer isn’t working, need shorter or longer or different size restrictor, I used autozone defoulers.

I’m using the big daddies O2 spacers on my 25 GT with Kooks Catless long tube with 1500 miles on them no issues

I’ve heard good things about them. My concern is that it is an exhaust leak throwing code. See attached picture of moisture after I pull car out of garage each time.

I almost always have moisture drip from exhaust on my vehicles, to me that’s normal and I have had a header leak and my H pipe came loose from a connection and I didn’t have any check engine light or codes from that, I’m guessing it’s the O2 sensor, Lethal Performance also sales a very good 90 degree O2 sensor

I went to their web site and see that they sell three types:

(1) Minicat,​

(2) Angled, and​

(3) Straight.​

Which ones are you running with no issues?

I would get the mini cat angled for better clearance, I am currently using straight mini cat but it’s not ideal for clearance with the straight
