Things I have tried:
Unplugging evap connector
Removing serpentine belt
probe all over with a stethoscope but can't really pinpoint it
The sound is weird as it comes and goes and it doesn't follow RPM. When I hit the pedal any amount the sound is gone. I recently put injector cleaner in the car and had afr issues. So I am wondering if while the car sat for a month with this stuff in it, if it possibly messed up injectors and they are making noise that echos throughout.
