an erratic squeak that goes away when car is accelerated. Its not the belt, pulleys etc. and appears to come from the air intake area???

Tried listening to injectors intake and airflow it does sound like its any of those.  It also does not seem to come from engine mounts.

Check Engine light is not on & car appears to run fine but the squeak is loud and annoying
