00 NHRA trans am hissing near intake So today I start my car as I would any other day. It started fine and drove normal but as soon as I come to a stop and the car drops to an idle it acts like its trying to die. As its having trouble at an idle I pop the hood and notice a hissing noise coming from the intake/throttle body area. Any ideas on what this could be?
