i searched it but i couldn't find a problem that was exactly like mine. i have a whistling and rattling noise whenever my car is idling. once i step on the gas, the noise goes away. ive dealt with it for a few months, however today, the whistling got a lot louder and my idle keeps dipping lower. i noticed the rattling and whistling only makes noises when my idle hits about 700-800. its getting super annoying and as i was driving to work today when the whistling was getting loud at a red light, my check engine light came up. any input? i adjusted the TB to have my idle higher so that i could avoid the sound, however nothing changed.

 

any help would be appreciated guys
