Hissing sound from intake manifold
Hissing sound from intake manifold
Hey guys I just noticed yet another problem in my Evo
So before I start the car and put the key in the ignition I can hear a hissing sound coming from the front of the engine by the intake manifold? It sound like I'm losing boost but my car isn't on. People were saying it's a vacumm leak because the vacuums tend to fall off but I can't seem to see any hoses off. Should I try by looking under? I'm not sure what to do but it doesn't seem to mess with the car it runs fine

That is what I was thinking also because it is not started. It has to be fuel related but I'm not sure what. Should I trying getting a new fuel pump?
