08 Grand Marquis throwing P0300 code.

Cylinder 3 misfire. Where do I start without spending a whole lot of money? Misfiring mainly at cold start and idle.
Also battery light comes on during idle. Airbag light is on. Abs light. And brake light. Alternator reads good. Battery reads good. Where do I start
