Hey guys,

Recently I've noticed a hissing/air sucking sound coming from the driver side of my engine (2005 na Crossfire Coupe). You can only hear it with the hood up and getting close to the engine. It occurrs intermittently and some what random but does not go away. Car runs great besides that sound. No codes. I do have a catch can but it does not appear to be coming from it or my CAI and I've had them before and no noise.

Any help?

Thanks!
