Default CEL P0304, Help please.

Had my turbo replaced 3-4 weeks ago, replaced with another stock. Today I've got CEL P0304, got it while driving and while boosting lightly. The car has a rough idle, with windows down at idle I could get a hint of a gas smell. I think it's multiple cylinders because there was another CEL but it was the same code. Any suggestions? Thank you.

CEL will flash, and sometimes stay on.

Misfire on cylinder 4. Swap coil from 4 to 2 and if it moved to 2 you got your culprit and erase code. If that doesn't wrk ten try plugs. Then injectors if if still no Beuno you might have a cracked ringlands maybe
