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

Why is there an intermittent loud hissing noise from engine compartment, usually just after startup?

You just hear it better if you lower the roof or open your windows. It could just be your air intake. Unless your rpm`s are really racing to above 2500 or it is at high idle for a long time, you shouldn't kick it down. When it is cold your choke is helping to warm it up quickly. Nothing is really working properly until it reaches normal operating temperature. Let it warm up. If you are still concerned, listen under the hood for better perspective and when in doubt, take it to a professional.

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.

My 97 dodge interpid idles way to high.can u tell me how to idle it down. and tell me where to look.

I would try looking under the hood for a vacuum leak. with the engine running try to listen for a hissing sound, or if the engine is to loud to do so look around at the rubber vacuum lines and see if any are dry rotted and or cracked. If everything looks fine it could be the Idle Air Control motor mounted next to the throttle body, hopefully you don't have a cracked intake.

2002 altima idling too high check engine light on

The first and easiest thing you should do or have someone do, is check under the hood for a vacuum leak, possibly coming from a cracked or broken hose. Check and inspect all rubber hoses, including the large ribbed hose running to the throttle body (Engine air intake from the air filter box). You can hear a leak if it is loud enough and will sound like a hiss. Your engine is idling high because of a vacuum leak.

When in park idle runs high, also sounds loud when shifting

Sounds like you have a major vacuum leak someplace under the hood.Look for any hoses that are broken or came off. You should be able to hear aloud hissing noise if you have a vacuum leak,also could have a intake plenum gasket sucked in or a stuck open EGR valve.

My car idles at 3 and the brake is stiff

Sounds like you have a major vacume leak, Chk. line going to break booster. Do you hear a loud hissing or whiseling noise either comming from under the hood or under the dash especily when you apply the break? If under dash could be bad break booster, if under hood still could be booster or a break in the vacume line from engine to booster.
