When i hit the gas theres a hissing noise coming from the passenger side ofmotor. It does at the beginning of each gear then stops, and starts when it shifts into the next gear

no its coming from the back of the motor, haynes manuel says something about the air supplypump

this is my first car with a CAI but i dont think thats it. I thought about an exhaust leak but not sure

Also i didnt think a CAI was that loud ?

Have you just recently added anything to your car or did this just randomly start? It might be your exhaust set up. An O/R (and even I think a high flow catted) mid pipe will make sort of that sound, and I can only imagine headers would amplify it further. I have a sound kind of like that. Is it only when you hit the gas, and most noticable at lower RPMs?

thats sounds exactly how this is, I bought the car with everything already done to it.

Honestly i was already sold on the car when i saw it and didnt notice the sound when i was test driving it

It's probably just a combo of your CAI and exhaust. If you can find someone familiar with stangs, especially modded you can have them take a listen, but it sounds normal to me.

I'll try to take a sound clip of my car when I go out in a few and post it up later tonight or tomorrow so you can compare.

I also have an air hissing sound in my car but it does it all the time, not only under throttle.

What about it? I need to look into it.
