1995 s14 hissing sound from the dash - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So jump in the car this morning all good then hear this hissing sound from the dash than temporarily goes away when pressing the throttle down.

Much clearer around 35 seconds or so.

Any one have this issue and how did you resolve it?
I have not changed a thing on the car in several months.

Thanks,

Since you already have a ballpark idea where it's coming from, why don't you remove the radio bezel and take a look in there ...

My guess, it's the Profec B or the Vacuum line running into it.

if it goes away under throttle does it get worse when pressing brakes? if yes you need a new brake booster, if not then yea check the boost controller lines.

Family member fessed up and said they knocked the vacuum line off. Fixed now.
