Engine weird Noise, Need Help!
Hi everyone, I have a noise that comes from the top end when initial acceleration is applied. when I feather the accelerator pedal both on and off...it has a desieling sound.
Also, when the car in high rpm, there's a air hissing noise. Can be heard from inside of the car, but not loud. I found this nois come from the driver side of the engine compartment. Also, evertime when the engine shut off, right that moment i can feel air been blow out, is this normal?
please help, thanks

I experienced a similar thing last night with my car for the first time. After shutting off the engine, I heard air blowing out from underneath the car in the area directly below where the shifter is or somewhere around there. It sounded like it was pulsating from long blows to short blows, like pshhhhhhhhhhhh..........pshhhhhhh......pshhhh..... ..pshh (if that makes sense) for about 5 minutes till it eventually died out. Saw lots of water dripping down in that area as well so I'm thinking its probably the A/C.
