Been chasing down a misfire for a little while. Bought new plugs ngk 5682 i think. Gapped them to. 22. Originally my msd80 blew so i replaced it with an 81. Fixed 1 problem but revealed another problem. Im still misfiring in cyl 2,3,4. Swapped coils and misfire is still in same cylinders. All injectors and coils are almost brand new from fcpeuro. Is it possible i could have installed injectors slightly off creating a gap in the seal at the tip? Here's a log. I d I nt k ow exactly what to look at considering cylinder correction and stft/ltft. The car isn't reaching booat either but im down to 2 last ideas before i say i dont know. Tbe wastegates had so much play i fixed the rear but have yet to get to the front. Also i noticed some chipping on thw rear turbo blades thinking that's contributing to the loss of pressure.
