On every start up, the motor drops below 1000 rpm to about 500- 700 rpm and the boost gauge goes up. once the motor is driven for about 3 minutes, it will stop and idle perfectly. Is it the mass air flow sensor
look at the video, the motor starts to want to die then the mass air flow sensor make a noise


also, the clutch is making noise

Sounds like your idle speed valve is gunked up. Try removing it (kinds hard since it is under the intake manifold) and spraying the inside of the valve with throttle body cleaner.
