I have multiple codes. And loss of power

What is your question?

There are random codes appearing on the reader. I get codes from random misfire at cylinder 1, 2, 3, 4, speed sensor out of range, TPS out of self test range,Air idle controlsystem at adaptive clip, Throttle/pedal position sensor/switch a circut high input,IAC System underspeed detected during self test. Any idea why so many codes, all at once combined with a loss of power. Where do I look?
