The large vacuum leak will be what is causing your engine to die. Some tube, hose etc has come loose in the intake system and is allowing too muck air into the intake manifold, so much that the air flow sensor cannot compensate for it. Open the bonnet and look under the hood for any obviously loose hoses etc by tracing the air from the intake to the filter to the maf to the intake
Have you recently had a large backfire? This can blow apart an intake if there are any plastic bits in it's construction, and that will certainly cause an enormous leak. If nothing is obvious you will need the help of a mechanic....perhaps to scan the computer for the fault codes first?..

SOURCE: 1994 Buick Lesabre service engine soon light. Can't read code.

I found several shops in my area, Albany, NY that had the older code readers. It worked fine, and cost me $30.00. It showed a bad O2 sensor that I replaced myself. I suggest you go to a reliable shop. Auto Zone/Advance etc.. do not have the right code readers. Joe

generally you just unhook the battery for about 15 minutes and hook it back up... if you have an anti-theft radio... make sure you know the code and how to enter it.

SOURCE: how do i reset my check engine soon light 2005

you can buy a code reader from an auto parts store that will give you the ability to reset the check engine light, or most parts stores have one that they use on customers cars at no charge. if you ask them to read which code your car is throwing, most of them will let you hit the button to clear the code. they aren't supposed to do it themselves for some reason, but from my experience they will let you.

What is a vacuum line in a Nissan murano?

Vacuum lines are on the engine for several different reasons. Power Brake boosters are connected to the engine by a vacuum hose, other vacuum lines go to the emission system and other engine controls.

You can spray those hoses/line with regular carb cleaner with the engine running, and if there is a leak, you will notice the engine changes RPM's when you spray near the leak. Only do this in an open area and in short burst. The "cleaner" is FLAMMBLE, so test one area and then let it air out before moving to the next area.

Reading the OBDII engine codes may help you pinpoint the leak by saying it's small, large, or, from a specific component.

The gas cap not being tightened properly, or with debris on the seal can trigger an engine light also, check that as well.

Electronic throttle control

Well, that's a difficult one. I would start by searching for a vacuum leak. Get a squirt bottle with some dish soap in it the rest filled with water and start spraying around the area that has hoses and see if any bubbles are present. With the engine running and try and stay away from electrical fittings and the alternator.

Service light and engine management light on constant on my sons renault megane vf1BM0H28

When the service engine soon/check engine light comes on you in most cases will not feel the engine run any different except in the case of a misfire or a large vacuum leak. What must be done now is to have the engine control module scanned to see what fault code is stored, when ever the light comes on a code is set in memory.

The 'service engine' light comes on and a computer reading says 'large vacuum leak'. There is no performance difference unless the vacuum thing can cause one of these; (1) on three occasions the car would...

Go to local auto parts store and have them do a code check for you.  I know here where I'm at they do it for free, and can tell you right off the computer what the code is and possible things causing the code or codes.  Then you can go from there ad maybe fix it yourself, and save a ton of money.Here we have Auto Zone and Advanced Auto, they both do this for free.

No heat frim 2004 nissan murano

Check your coolant levels 1st, on both cars. If you've already changed out the T-stats, then you need to move on to the temp sensors, might be bad, but if your check engine light is on, pull the codes and see where that points you.

2004 Nissan Frontier Service Engine Soon light came on

P0321 Ignition/Distributor Engine Speed Input Circuit Range/Performance. P1456 Leak Detected In EVAP Control System. Sounds like a vaccuum leak somewhere. I would clear these codes out and see if they come back first. Then if they do I would check to see if you have a vacuum line loose or broken off. If they codes stay off it would be ok to keep driving the truck, but if they came back I would definately get it looked at.
