Hi.

Often this problem is caused by defective MAF sensor or AIT sensor. Both sensors are located on the air intake, and determine how the ECU will mix fuel and air.
A vacuum leak can also cause problems of this kind.

the best thing to do is going to the nearest Auto Zone, and asking a scan code reading. The operation is free of charge at Autozone, and will give you error codes that can help locating the problem.

When you get the error codes, write them and get back to us, so that we can tell you more on the problem.

Regards.

SOURCE: runs good when on the gas but wont idle

Dear 24scott,

This sounds like it may be as simple as cleaning the water or gunk out of the gas tank which is what I always do 1st because it's easy and inexpensive.

If your fuel is contaminated with gunk, grime, water and/or bottom junk like rust this will cause stalling!

It's most likely bad fuel or clogged injectors so....
Fill the tank with High Test, Add some dry gas and a good fuel system cleaner or 2 or 3 and this should dissolve all the gunk and clean the injectors!
Read & follow the cans' instruction carefully.

If this cures the problem never let your gas tank get below 1/4 and especially never run it to empty as this is when the gunk and/or water will enter the system!
This Should FixYa!

SOURCE: wont hold idle will start with foot depressing gas pedal will run with foot on gas but stalls when foot removed

Check and clean Idle air control valve. Make sure its responding to signal as well. Also make sure ther are no vacuum hoses disconnected. This may not be a "cure" but it's a good place to start.

Car won't stay running, starts up and then just dies off like it never had a Chance of staying idle.


Hi Johnny, Im AL the owner of Big As Auto Repair.

Johnny, here's something I want you to try. I want you to start the engine while giving it a little gas, not much, just enough to see if it will idle. If it does Idle and stays running with your foot on the gas and dies when you remove your foot. Then go and buy an 'IDLE AIR CONTROL MOTOR" It mounts on the throttle body. Put that on, there are only two screws that holds it on, very easy to replace. After installing it the idle will be real high, this is normal, just wait it will stabilize and idle normal. NOTE: if it still dies even with your foot on the gas, then you have another issue but this is a good place to start. Hope this helps and please visit my auto-repair-website at: http://www.bigasautorepair.com/

Jeep 2002 grand cherokee dies unless i keep foot on the gas...


The idle relearn needs reset. Keep your foot on the gas at about 900 rpm. Make it idle for about 5-6 minutes. Slowly ease up on the gas until it will idle on it's own, it might take a while. After you get it to idle, it might be idling real low, but on its own, Let it sit and idle until for 20 minutes. After that it should be back to normal. You will have to do this every time you have the battery unhooked for a while.

Running problems


Idle air control valve or a vacuum leak, the idle air control valve controls the amount of air let into your engine when you start or while running you holding your foot on the gas lets more air in.

Car will not start without pressing gas pedal to keep idle speed up. If I keep idle at 900 RPM or higher it runs as long as foot is on gas pedal. It then stalls out when I take foot off gas pedal. No...


Have the idle bypass valve checked, also called idle air control valve.
If that valve is stuck in the closed position, it's not allowing the fuel to bypass the throttle plate to keep it idling, resulting in stalling, but will keep engine running if the pedal is pushed down.

In park the engine dies; only will run if given gas


It sounds like there is a problem with the Idle Air Control (IAC) valve. Its job is to open and let air into the manifold when the throttle is closed at idle. If it does not open, the engine dies at idle. The IAC is mounted on the throttle body. Possibly the valve is clogged or stuck, in which case it could be ok again if it is removed and cleaned. Or it is broken, and needs to be replaced. Or, there is a problem with its electrical connection, that needs to be traced. Good luck, let me know if you have any questions.

Engine starts, but won't idle, after I take foot off the gas


you may have an issue with the air idle control valve that allows air in the motor when you haVE your foot of the gas oedal. well it is actually an air pedal because it let more air in when you press on it and the computer gives it more gas. so if it runs and idles when your foot is on it and it won't if it is off then the air flow is getting cut off totaly and i would look at that idle air control valve or (iacv) good luck
