Not fuel starvation, but lack of air. Usually, the first code points to a faulty vacuum line or elbow. The second code is the MAF not working correctly or a leak in the air flow to the throttle body.
Open the hood, start the engine, and while the engine is still cold, listen for air leaks. Because the MAF is expensive to replace, try anything else first.
