1988 Suzuki Samurai Hissing Sound Under Hood

I have a Sammy that has developed an intermittent loud hissing sound under the hood. When the hissing starts it effects the idle and starts burning rich. I have replaced all of the vacum lines. The hissing is around the Carb. Can anybody tell me what to look for next. The vehicle runs great when going down the road but you can still hear the hissing.

Hi its definatley an air leak if you have replaced the hoses i suggust the next thing you try is see by tighting the carburrettors nuts that hold it to the manifold as these come lose and **** air do the same with the manifold bolts i suspect you will find them loose if not then change the gaskets one at a time with the cheapest first the carburretors then the manifold you may want to go to your car shop and ask for an air leak spray or they may use some other kind of method but basicly you spray it round the carb/manifold and watch to see where the leak is yates210456

When I hit the brakes on my 1999 Pontiac grand Prix the pedal will not go down


Do you hear a loud hissing sound under the hood while the vehicle is running? It sound as if the vacuum assist stopped making the pedal difficult to press. This is usually due to the vacuum hose going to it being disconnected or ruptured.

Under acceleration there is a loud hissing/suction sound as if there is no air filter on the motor.


If the hissing is coming from under the hood,you have a vacuum leak at one of the hoses,EGR valve on top of the engine, or a hose off someplace like the line going down to the transmission. An easy method to check where, is toget a can of spray starting fluid, and spray a tiny bit in a few places around the engine. When you hear the engine rev up,your very close. If the hissing is inside the cabin, check the hoses at the climate control or the blend air door motors.
