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
