Default Rough idle, Alternator?

When my truck is in park my RPMs tend to drop then come back up repeatidly and im not sure whats causing it. When i listen under the hood I notice a noise coming from the alternator. Also when watching the engine it moves a little when the RPMs are dropping. I'm thinking that the brushes in the alternator need to be replaced... Any suggestions just let me know

try cleaning your maf sensor, iac sensor and your throttle body. my truck did the same thing.

IAC is a valve not a sensor
