Boost or Vacuum Leak
I have a 1991 gtir and when I turn the car on there is a hissing sound when it is idling and then when I put my foot down and get past 2500 rpm it starts hissing again and I can find out what the problem is, it is coming from right on the back of the engine near the firewall









lost one of your vac hoses off the distribution block
