WTF is this noise?

[Trogdor]

For a while now I've had this vibrating/rattle type noise coming from my car. I finally narrowed down the conditions under which it happens. What are your thoughts on what it is?

It's only happening from about 2.3k-3k RPMs. It only happens a lower speeds. It's typically 1-3rd gear that this happens. It does not happen when the car in is neutral and I rev the engine to that same RPM range. And generally is more prevalent when the car has first started.

Plastic rattle/buzz noise? I went through my interior with Presto felt and that helped cure a lot of the rattles. The little hydraulic arm on the glovebox is notorious for rattling.

No, I've done that too. Amazing what $5 spent at JoAnne Fabrics will do to a $35,000 car. Pretty sure it's from the underside of the vehicle.

You work at a dealership, your car is under warranty, have them throw it up on a lift.

X2 isn't that the perks of leasing? Not having to deal with the issues?

Boost solenoid or some other solenoid buzzing? Exhaust or o2 sensor hitting underside of car?

you could do what everyone else does on this forum, get your hands dirty and look under your car for something that rattles or moves enough to be hitting something else. Why not inspect before asking questions
