this may help you out. but i was having a problem similar to that on the warm up with out the chirping noise. but you may want to try and clean your mass airflow sensor (MAF sensor) its really easy to get to and all you need is brake and electric motor cleaner. (i got mine at napa) all you do is take the cylinder that houses the mass airflow unit out of the air box and spray the sensor. let it evaporate then reinstall. i did this to mine and slapped my self in the head when my car ran smoother down the road and ran smooth while idling. hey its worth a shot.
