Vacuum leak

Symptoms of engine vacuum leak: The problems that arise from an engine vacuum leak can be more than annoying. Idle speed that is way too fast is one of the difficulties, and stalling is another. Confirmation of an engine vacuum leak can be a very loud hissing sound coming from the engine area.

Could a vacuum leak cause right bank #1and bank 2 to run lean?

Running lean indicates too much air (like a vacuum line leak or an intake manifold leak) or not enough gas (like low fuel pressure or clogged injectors)

I would check the fuel pressure. Autozone and others will loan or rent fuel pressure testers. If fuel pressure is correct, purchase a vacuum gauge for about $15-$20, and hook it to a manifold vacuum tap. If your vacuum reading at idle is less than 17-22 inches vacuum and steady, then you have a vacuum leak. It is a great diagnostic tool-tells you quick if there is an air leak somewhere. Here is a link about using a vacuum gauge:

If you vacuum reading is good, check the injectors.

2003 trailblazer, 4.2..... No vacuum to the fuel pressure regulator. Why?

vacuum leak at intake or maybe to brake vacuum booster. Usually able to find with carb cleaner. Once the carb cleaner enters at vacuum leak it will raise the rpm's then you know where to look for the vacuum leak.

Engine stalls essesive gas consumption

When does it stall? Give me some more details. But in the mean time Im gonna guess vacuum leak. Turn the car on and spray carb cleaner at the vacuum hoses. If you hear the engine wind up you know there is a vacuum leak in that spot. For your engine to stall and take a lot of gas its gotta be a big vacuum leak. But it might not even be a vacuum leak but its something to check into. It would be a cheap and easy fix if it is just a leak! Give me some more details if its not a vacuum leak. Good luck!

I have hard break peddle with little breaking power. I checked the vacum pump a found 13 inches of vacum. the hose removed from the vacum booster will **** your finger to it with motor running. the truck...

Hello, Check other Vacuum lines for leaks. If you have a 4x4, they can have Vacuum operated hubs and a leak anywhere will draw down the Vacuum. I found most pumps running at about 21psi. Check for a Vacuum Reservoir. The older models used one looking like a coffee can and they would rust on the bottom and leak.

If you take off a vacuum line and use a hand vacuum pump, you should easily find a leak on one of the remote lines. Another test idea is to remove the Vacuum pump lines, put in soapy water, and pressurize with about 3 PSI. Any vacuum leaks will blow bubbles and soapy fluid. Its your choice on what to do. I would reserve the soapy water for a line I find to leak with a hand Vacuum pump.

Many of the people wih your problem replaced the vacuum pump and were good to go. But if you can measure the vacuum and find the leak, you may save money on a part you do not need.

I hear big vacuum leak on 2001 elantra not any hoses

If you can "hear" a vacuum leak then the performance of the car would be greatly affected and the engine would idle much higher than normal. Normal idle speed is around 800-1000 rpm, Check you dash tachometer. If you have a vacuum leak the idle will go up to 1200-1500 rpm.
There are lots of places beside hoses that can leak vacuum such as the EGR valve or around intake manifold. But check that rpm's first to confirm what you are hearing is a vacuum leak.
You can also purchase a vacuum gauge form your local auto parts store. they cost around $20.00+. The gauge should read a steady 15-20", if less, then a leak is indicated

In the past we have used starting fluid to find vacuum leaks. Start the engine, let it idle. Spray quick shots of starting fluid at your vacuum lines in isolated areas. When the starting fluid find the vacuum leak the engine will react to it... usually by going up in rpm. Depending on your engine computer, it may stall the engine. Either way you will find your vacuum leak. Get starting fluid or "ether" at Autozone or O'Reilly.

Vacuum Leak, the car jurks sometimes while riding.

When the problem is a vacuum leak you also have troubles at idle.
The vacuum can be tested using an hand tool gauge like this.
Vacuum/Fuel Pump Tester Kit
Once you find the leak, replace the leaking part.
Often it is easy to find the leak at a glance, as it is hissing or you notice the air out from the leak. Other techniques are pumping smoke inside vacuum or spreading soapy water on vacuum lines.
check also the EGR valve.
If you need the vacuum system diagram purchase a repair manual like this one : 2000 Cadillac SeVille STS Repair Manual on CDROM .
Here also a free tutorial on vacuum problems.

you have a vacuum leak. Check the vacuum reservoir for a leak.

You can spray short bursts of starting fluid on the vacuum lines to find a leak. When engine revs, that's the leak. Be careful.

Vacuum Reservoir Tank and Bracket Removal
  1. NOTE: The A/C vacuum reservoir tank and bracket (19A566) is located either on or beneath the RH front fender splash shield (16102) .
    If the A/C vacuum reservoir tank and bracket is visible from above in the engine compartment, perform Steps 2 through 4. If the A/C vacuum reservoir tank and bracket is not visible in the engine compartment, perform Steps 5 through 8.
  1. Remove the screws and the A/C vacuum reservoir tank and bracket. 1b32ebf.gif
