I hope that the o2 sensors are at fault, as they are an easy fix, and will cause the symptoms displayed in your video.
IAC and
MAF faults are not common and are usually very reliable on these engines. If I can make a suggestion, only use NTK o2 sensors. They are OEM and are super reliable for long life. No other manufacturer, including Bosch, can match them. Even though they will be accurate for many years, I replace mine with every spark plug change. Your fuel trims, and therefore fuel economy, are totally reliant on their accuracy. Just my 2c.
