Misfiring, rough idle, no acceleration, etc

[daltron]

Tons of issues. It's misfiring, the car can't accelerate properly, but once it is warmed up if you are really light on the gas pedal and let it upshift before 3-5K is seems to drive slightly better, can't rev high even in neutral, etc.

Codes are 0073, 0101, and 0300.

I've changed the plugs and ignition wires and it went from pretty much undriveable and dying at idle to what I described above.

Where should I start?

0073 is for the Ambient Air Temperature sensor, and 0101 is for the Mass Airflow Sensor. I would likely start with the Mass Airflow Sensor.

I have a 2008, forgot that. I thought they didn't have a MAF? I can clean the air temp sensor and throttle body though.
