Okay so the code is #51. Lean fuel mixture or something like that. Long story short comin home from work I was on 2 cylinders it seemed like, hit a bump and out of no where I gain all my power back, hit another bump and then went to 3, then back to 2 cylinders. I also found this when I looked at the air filter, it was like a sludge almost from the vent tube. 
I check my fuel pressure earlier in the week and it was at 29 psi while at idle. I’ve tried chem tool injector cleaner, 91 octane gas, checked cap and top of rotor, plugs (slightly brown but still in good working order). And the air filter. The sludge in new.
Everywhere online I’ve looked has pretty much every answer known to jeeps. What do you think? Map? O2 sensor? I was thinking injectors until the bumps in the road changed how it ran.
I ran through over half a tank in under 60 miles when before I could run over 200 miles before refill consistently.
At the dealer before I got it they replaced the fuel tank due to warping and the the return hitting the bottom of the tank, found metal in the bottom of it, also replaced the pump assembly. The note for that was running rich and cuts out under load via code scan.
Replaced fuel pressure regulator.
Replaced fuel pump module and gasket.
Also has a new o2 sender on the pipe before the cat (I think that’s the 02 sensor?)
Only other thing I can think of is it got worse after I took it out last weekend and played in the mud a bit.
Please help, I don’t have the money to be buying parts just to diagnose the issue. Unexpected bill hit and I’m out for 2 weeks. I have cash for buying what is exactly needed that’s about it:/ especially before the New Years trip!!![emoji848][emoji58][emoji29]
TIA!
