Might be you have a bad mass air flow sensor or the snorkel from the mass air flow sensor to the throttle body could be ripped, it can cause your vehicle to loose power along with many other drive ability issues. If you need more help on how to repair your mass air flow sensor, I would suggest checking out this site How To section Repair mass Air Flow Sensor
