There is no typical. Try this, even though if anyone sees you they will laugh: Take a piece of hose, Heater hose, garden hose etc. Put one end to your ear and "scan" the engine while running with the other end. It will help ;you "dial in" the location of the leak. Then, fix it!

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!

You might have a possible vacuum leak. open the hood, let the car idle and listen closely for a hissing noise. Possible cracked or broken vacuum hose. Is the ck engine light on? Or possible TPS (throttle position sensor), IAC (idle air control valve). I would check it for a vacuum leak first, if you do not find one take it and have a scanner put on it. Autozone and O'Rielly's will do this for free. Hope I sent you in the right direction. TJ

Whistling noise coming from the engine compartment on a 2006 Ford Escape. The noise usually comes and goes. Mostly when the truck is idling or when I accelerate. I've been told it's a vacuum leak. ...

a whistling noise will be a vacuum leak from some point. The Escapes are known for having vacuum issues in the rear of the engine due heat caused from the motor. The lines dry and crack out.

Air conditioner gets stuck on defrost and the cruise control stops working at the same time.

Vacuum leak for sure. Check the vacuum lines in the engine compartment. Specifically near the fire wall for any cracked lines or broken connectors. Also look at the vacuum resevoir for a crack. You can also assist in locating the leak by running the engine and listening for a hissing or sucking sound. Let me know if helps. I would need to know year and moel to help mire if this first go around doesn't help.

Why does my 2001 Ford Escort run rough and often die at an idle but seems fine oncethe RPMs are up?

There are two likely possibilities. One is a leaking vacuum line. Inspect the vacuum hoses closely. Listen for any tell-tale hissing sound. Oftentimes the culprit is the hose going from the PCV valve to the intake manifold. It is susceptible to cracking. While you're at it, check the condition of the PCV valve.

The other possibility is a faulty Idle Air Control (IDAC) valve. If the IDAC is not opening sufficiently, the engine will idle rough or die at idle. Try removing the IDAC entirely, so the air intake is open. If the engine idles ok with the IDAC removed, replace it with a new IDAC.

If neither one of these possibilities checks out, you will need further trouble-shooting.

2003 malibu engine idle @ 3500 rpm vs approx 500 in past. Sudden onset. Engine warm. Odour. Attempts to reset by giving a thrust of gas while in neutral do not help.

Your O2 sensor may need replaced. They are located on the exhaust, Typically 1 is infront of the catillic converter and one after. I would start there!
Good Luck!
