Problem Description and Possible Solution
A faulty mass air flow (MAF) sensor can cause erratic/rough engine operation and fuel economy issues. Since this sensor measures the actual amount of air entering the motor, when it fails, the engine control module (ECM) takes the wrong information and delivers incorrect volumes of fuel to the cylinders.

runs poorly, with rough idle, has no power when driving. How often should I spray the sensor and or do I need to change wires?
I have a similar problem, especially when the car sits for a while without driving. I always keep a can of MAS air spray in my car. By removing the cover over the MAS unit, I spray a small amount into the unit; it works like a charm.
