    So I've noticed the last couple weeks when I first start my truck in the morning and start to back out of my garage, and the best I can describe it, a strange vibration sound, a "BRRrr" for a few seconds coming from the front under the hood. It stops a couple seconds and does it again a few times. Once I put it back in drive, it sometimes does it right then, and then I dont hear it the rest of the day. It only seems to happen in the morning.

    Any idea what it could be? I dont have much left on my 36K warranty so need to get it checked out soon. Thought I'd get some info here before calling the dealership. Thanks..!

    Listen for something like a Hoover in the passenger side wheel well. That'd be the Secondary Air Injection Pump, and would be a component of the emissions system that operates at cold start up.
