Fark I might be fuel actually.... It's not the same kind of power drop that I experienced when my stock coils died...
Fuel pump is an in tank Walbro.... I think its a 255L pump
AFR's on the tune looked alright, I'll upload a pic of the AFR graph when I get home.
This is the misfire when my coilpacks were dying.... The power drop is similar, but no sound, which would make sense if there was spark, just no fuel to burn....
