Default Misfire

So My number one cylinder is misfiring. I switched around injectors and spark plugs, I cleaned my coils. I did noticed it misfires when shifting at high RPMs between 2 and 3 is that a PCM thing. Can that be tuned out? I really hate when I grinding a intergra under my tail pipe and I have ot back off cause he engine lights starts blinking.

You mentioned coils, plug and injector. What about the wire?

Have you swapped another wire in place though? I'd give that a try.
