I would start with the Mass Air Flow sensor. It is located on the air intake line just after the air filter on the way to the engine. You can take the lines off both sides of it and spray it out with carb cleaner. You will have to clear the codes after that. If that doesn't fix it you might have to replace the Mass Air flow Sensor. Hope this helps.

The Po300 is a random misfire code where the PCM is picking up the misfires. The other two codes are lean mixture codes. More than likely these are due to bad intake manifold gaskets allowing unmetered air to enter the engine causing the engine to lean out and possibly run a little rough when cold.

Check the intake manifold gaskets for leakage. It will tend to run rougher in the morning when it is cold. Check for vacuum leaks on any hose connected to the intake plenum too.

171 and 174 are lean mixture codes, 300 is a random misfire (any cylinder). Check for a vacuum leak, listen for a hissing noise with engine idling.
