You either need to get some info for the guys here or do like you plan and just start throwing parts at it which isnt really recommended.

As for the emulator, youre better off buying a PCM with the code removed. Idk, I never liked the idea of giving the car false info.

yeah I’m really not trying to throw parts at it but I bought a fuel filter for it a while back but I haven’t put it on yet since the old one is a wee rusty and the o2 sensors are definitely bad I’m really lost about this misfire and why it’s running lean but with what I know and what you guys are telling me I’m starting to get ideas here and as for the emulator deleting the cat was a better financial move for my situation so I’d rather go this route then get a new cat lol

You're fine emulating the rear cat code. That sensor shouldn't affect fueling, the upstream one is the one that does.

Okay makes sense so I’ll replace that one and grab an emulator and put my fuel filter on and we will see what happens!

keep you all updated thank you!
