Chirping noise?
 

Whenever my car is in motion, I hear a low-sound chirp, kinda like a beep beep thing. But whenver I'm at idle, it's gone. Not sure where it's coming from, but it sounds like it's coming from where the door ajar beeps.

I think my car is telling me something. Anyone else encounter this?

is it at all times when running or just on decel? i remember reading that the shutter valve will make a chirp on decel if its bad. Im sure someone will correct me but it's something to think about.

When I press on the gas, too. This sound it's not so loud. It's like my car is trying to tell me something...maybe put it out of its misery?

oh ok lol, sounds like my FC before i tore it apart...

The faster the car moves, the faster it chirps, so when I decelerate the chirping sound slows down. Sounds like it's coming from the dash.
