So I just put a new engine the car and some 17ts the only codes I’m getting is from a rough idle and rough under acceleration. The car has a brand new walboro 525 and the lpf and the hpf are reading fine attached are the short term fuel trims which look wrong to me I also will attach a log on spool street. I’m also getting timing corrections in basically all cylinders. https://*********************/graphs/l...2-27-05.41551/

one (or more) of the injectors in bank 2 could be leaking quite a bit...

I was thinking that I was getting a light smoking after while.

Replaced those two injectors with a couple I had still missing on 4 and 5

Replacing fi blindly is not the solution. First, the car sits for a while and the spark plugs for each cylinder on that bank are checked.
If the plug smells of gas / running black thats the giveaway. Only then the fi should be replaced w known good. Otherwise issue could be something else,

[Aaronms29]

I replaced them with known good injectors I’m getting a plug socket atm to swap plugs to see if the problem follows. When pulling the coil pack nothing changes. I’ve swapped the coil packs with known good aswell.

[Aaronms29]

At this point I’ve swapped the plugs, coils and the injectors (with new) the plugs and coils with known good ones from other cylinders. The issue still remains misfires on 4 and 5, at one point I unplugged 2 of the 02 sensors and it seemed to clear up a bit I would see on bank 2 afrs with them plugged in would be at 30 after unplugging them it would return to 15 as normal when plugged back in would jump up again. Any thoughts appreciated Sgop335

re read and comprehend the post and comment on condition of All spark plugs in bank2

They were black but not wet and did not smell of fuel.

What tune are you running and what fuel? The STFT you have pictured is very low, it’s possible your tune’s fuel scalar table is incorrect for your setup
