Need new coils? Fuel injectors? Plugs?

It was a bad coil.

Thanks @nachob for response.

Summary of issues:
Cold starts can be rough and I have some shake on idle, today it was real shaky, I started car then had to shut off, started backup it was shaking and sluggish.

Stopped and started again, it ran OK, but car felt sluggish service engine light on, drove around stopped and waited two minutes, then car felt normal.

Left work and light was still on, car ran fine, drove it pretty good on a Broad.

Ran Carly through ODB port and got the above code.

Mods: MadDad MP, BPM tune.

Any input is appreciated
Coils are most likely the culprit. You can swap them around to see if the bad cylinder is working again. I hope that's the issue!
