Default CEL Code Buffet.

I bought a 2008 Saturn Astra. Had it for five months. CEL finally popped up and it reported 5 codes.
Pulled from an Actron reader.

First is P065E Intake Manifold Tuning Valve Performance (Bank 1), this code was listed twice.

P1101 Intake Airflow System Proformance

P0128 Coolant Thermostat (Coolant Temperature below thermostat regulating temperature) - signal invalid

P2A00 Oxygen Sensor circuit range / performance bank 1 sensor 1 - signal invalid

P0135 Oxygen sensor heater bank 1 sensor 1 - short to battery

4 other codes are pending but I didn't take a picture of them.

I don't even know where too begin. I think this may be a vacuum or ground problem? Possibly a cam sensor?
I check the battery cable and there isn't any play. Car operates pretty well just not shifting as smoothly.
