Hello!
Codes: P0171 System too Lean (Bank 1)
P0300 Random/Multiple Cylinder Misfire Detected
P0301 Cylinder 1 Misfire Detected
P0305 Cylinder 5 Misfire Detected

Check clean: IAC Valve (idle air control valve)
EGR (exhaust gas Recirculation)
Oxigen Sensor bank 1 (before cat. Conv.)
MAF sensor (mass air flow sensor)

Those codes are sensor related.
After check and clean process erase codes and see which one return.

Let Us Know!

99% chance the airflow sensor is bad.
