Dashboard Christmas Tree Help

[Mintmoney15]

Hello all. Today I turned my car on for the first time in about 24 hours and drove about 30 feet before my dashboard lit up. My check engine, brake system, steering and traction control light all turned on. I turned back to my house and used my ktunner running tsp tune to check for an error code and got p0303 witch is cylinder 3 misfire. The last time I drove the car I drove kinda hard for maybe 5 minuets. Looking for some help on why all those lights would turn on if it’s a misfire and what to do. Thanks

How’s your battery voltage as well?

As suggested, verily battery condition.
When I tuned my car, it threw ever warning light for the first few miles until the car ran through all its checks.
I was warned this would happen, but your heart still jumps to your throat when it occurs.

I’ll definitely check the battery but if that’s not it is there anything else I can do or do I need to take it in

Looping in the expert, @gtman.
I think\hope it's just your battery.
