Anyone know what this is exactly changed injectors spark plugs o2 sensors maf sensors and still none even switched over my HPFP cuz bank 2 looked like it was running richer then bank one determined that from taking out the spark plugs bank 2 was burnt with fuel and still none. Car has stage 2 tune with catless downpipes and a cold air intake. Car acted weird a couple days after intakes anyone think that's the issue ? Did a smoke test no leaks. Engine has a rough idle spark plugs are new and rpms jumping
