Do ya hear any hissing sound nearby the Air flow meter?
I'm pretty sure I got a leak somewhere but I can't trace it.. I was wondering if anybody else had or has a problem like this.. It's hard to tell when you are driving or inside of the car. You have to pop the hood to hear the sound..

That probably means 37 people with no hissing. None here.

Sorry I didn't see this thread sooner.

I hear somewhat of a hissing/suction noise towards front of the motor on the driver's side near the intake tubing. Is that what you're referring to?

Mine is coming from back of the motor by the AFM.. It hiss for like 1 sec then stops then does it over again..

weird eh..I've noticed that engine sounds a little different too when RPMs go down..

This is an off-topic question but I got my wheels aligned by dealership 3 months ago and now the car is pulling slightly towards right... Does dealership usually align my wheels for free or do I have to pay another $90?


thanks

I wouldn't worry too much about the hissing noise if you're not experiencing any drivability problems or Check Engine lights.
