Check #2 plug and #2 plug wire.

Or move the coil and plug to a different # and see if the code moves.

Okay guys, will do that, but any idea why this happened directly after cleaning the maf sensor? I haven’t had any misfires at all before.. my car is on 130k miles and I have never cleaned the maf before, might this be happening because of the changed air/fuel ratio?

Unrelated, unless you shifted the #2 wire or hammered the plug when doing the work.

There's a high chance of just coincidence. Have you done plugs or anything yet? Super easy on the LFX, and could be a good time to just take a look and replace.
