Okay I have a 16 2ss with headers, no cats, rotofab, ported 95mm tb, 2step, ported msd IM and e85...also 65k miles. I've had this setup for like 20k miles

I've been having a few issues over the last few weeks. I developed a misfire at WOT when I was doing pulls on the highway a few weeks ago. The car would break up after like 4 or 5k rpms. It didn't throw any codes though,, I just seen the misfiring on the torque app after I heard it. I don't remember if it was just one or a few or all cyls. Well I threw new plugs wires injectors and coils in just because, and my problem seemed fixed. One weird thing I noticed was that cyl 3 had ALOT of nasty gunk in it. None of the other ones did, I cleaned it out but that might be worth noting?

Fast forward to Friday, I'm in Mexico, I launch, all the sudden the check engine light and stabilitrack come on. Car is missing hard on cyl 3. I turn the car off and back on and it goes away. I try again and it does the same thing. The codes came back as p0267. So I plug my laptop with HP tuners in and try again, I don't know what all I'm looking at for the most part but one thing that seemed off was the driver's side bank 1 o2 was reading 0 at WOT past like 4k rpm... so today I replace that, and my problem is still there(it just doesn't read0 now) . I know msd manifolds like vacuum leaks so I took it off to put my stock ported mani back on and no change. Also nothing off seems to happen if I do a highway pull it just seems to be from a dig or low speeds. I am running a 315 35 17 rear and a 275 40 18 front(is that an issue?) But I have had this set up for maaaany miles.

I know this is long but where do I go from here? The plug for cyl 3 injector looked OK but I don't know.. this is extremely annoying Lol

I fired the parts cannon once again and replaced the whole fuel rail+pressure sensor+wiring just because and it seems good...i have no issues now no misfires no lights and its running good....for now

Also amazon has the whole thing for 100 bucks if anyone in the future ever needs it.

No problem, I often find unfinished threads when I'm trying to figure out something and it's sooo frustrating so this is the least I can do 😭

Everything has been well....

Until today I was about to launch, and my car launched Coolant everywhere. If pour it in the reservoir it immediately goes out the bottom of the car ������������

P0267 and misfire has returned, smh, not sure what to do from here
