Default Need some help with consistant misfires on cylinder 6 and rough idle

got these codes:

18010- Power supply (B+) terminal 30 low voltage
16684- Random multiple cylinder misfire detected
16690- Cyl. 6 misfire detected

So I cleared the codes and switched coilpacks on 5 and 6 and replaced the sparkplug and 6. There seems to be slightly less misfires on 6, but still way more than any other cylinder and the car feels to be idling rougher than usual.

What should I check next? Any ideas?

Are you stock ? If not do you have a stock ECU ? If yes, Try that.

Default Check all the plugs that are on top of the airbox. Try disconnecting the MAF.

See how it runs with the MAF disconnected.

Default Possibly a clogged Fuel Injector.

Good job in troubleshooting, by the way.
