If you know what a turkey call sounds like then you know what sound I'm getting. I hear it when I stop after driving, not after inital cranking. The sound gets more frequent if I give the accelerator a little push, but goes back to a normal once every two seconds if I let off. I'm dumb when it comes to cars. What could this be?

 

I have no idea but I am having vision of those AAMCO commercials where folks vocalize the noise their cars are making to the mechanic.
