Tried searching around for this and found a little bit of info. I sometimes hear a honking type noise coming from my engine, especially when its cold, and only about a 1/3 of the time when its warm. Is this coming from the DV's? or is there any other thing i should look at?

Heres and example: Its cold, I start my car to go to work, let it idle for 30 seconds or so. Give it a very little gas.. as I let off I get a "honk" type of noise.
