Hey all new here and was needing some help, and by the looks of it this is the best place.

I am having codes of P0304 and stability track is kciking off, with the engine acting like it running on 1 cylinder. It is super rough at low rpm and I have a obd2 sensor with a app, I am showing a 12.3 air/fuel ratio. I have replaced the coil pack/spark plugs, cleared the stored codes ran for about a week and back to the same thing but running a lot worse.

Thanks in advance for all help!

P0304 is cylinder #4 misfires. Check coolant to see if it drops. When you removed the plugs was #4 looking different from others?

Ok I am going thru this right now, check your brake switch. So far I have replaced coil pack, fuse block, abs sensor, tpms sensors, and after 4500.00$ worth of work the dealer says it's the brake switch.
