P0300 - Random/Multiple Cylinder Misfire Detected

P0171 - Fuel Trim too Lean (Bank 1)

You will definitely want to check your fuel filter to make sure it's not clogged, check your fuel pressure in the lines, and make sure your injectors aren't sticking close by bench testing them.

Let me know how it goes.
