P0101 Mass airflow circuit  Range / Performance problem

This would be a vacuum leak,when you disconnect the MAF, the system goes rich , use a carburator cleaner or brake cleaner to help find the leak it can be from the intake manifold, throttle body , When the leak is found the RPM will have a noticeable drop.
