Most low idle speed problems on these engines are due to a faulty idle air control valve but since you state the idle will go up and return to idle then i would say it is working properly i think you have a throttle body coking problem ( dirt and grit accumulates around the butterfly valve in the throttlebody ) to fix this simply remove the fresh air hose from the throttlebody and open the throttle all the way up use a clen rag and wipe clean you may use a solvent such as B12 on the rag but dont use too much 94 jeep grand cherokee. starts,idle. throw warmup. - 1_4_2013_4_54_06_am.jpg

SOURCE: 94 jeep grand cherokee stalls after the first 5 min of operation

Sounds like the automatic choke is either binding or gone bad.

On a cold start, that's why the RPMs are bumped up for a few minutes...the choke is allowing the engine to warm up, before dropping the intake mix to normal "run" level.

However, should the choke remain closed once the engine is hot, the stalling will happen for lack of air.

The choke-control is mounted on top of the manifold, near the throttle cable-cam.
Look for a small (about 3" wide X 2" deep) cone-shaped metal can with a linkage to the throttle cam.

With the engine off, spray the linkage at both ends with Liquid Wrtench and work the linkage in and out of the can a few times to check for smooth operation.
You should feel slight back-pressure when you move the linkage toward the controller.
With the linkage pushed in, spray and wipe the exposed surface inside the controller body.

Allow the cleaner to dry for a few minutes (it's just oil, I know...but if you used a spray, the propellants could be flammable) and start the truck.
Allow it ti idle at least 5 minutes until the auto-choke pulls back on the throttle...then take a short ride around the block to see if that cured the stalling.

SOURCE: 2004 jeep grand cherokee idling problem. Revs motor 200 to 500 rpms higher while driving.

I had the exact same problem on my 04 GC. I put some Techron Concentrate Plus Fuel System Cleaner in from Wal-Mart and it seemed to fix the problems right away. Let me know.

SOURCE: 2004 Jeep Grand Cherokee. Keeps stalling, engine

P0505 means the whole Idle Control system, not only the IAM. Check all related sensors (i.e. crankshaft sensor). Check with a voltmeter direct at the connector of the IAM if you get any signal. Remove the IAM from the TB, connect him, let someone switch your ignition key to ON. The IAM need to drive in/out for a short time to find the right position. Hold the IAM near a hard part, that they cant drive out completely! If IAM works fine, check the fuel pressure, check and clean your TB ( if not done yet). If that doesn't work, come back again please

Try looking at your air filter. You could have a vacuum leak, like you already said. Also, check your coolant sensor and intake air temp sensor, if equipped.

Hello;
Have you checked your fuel pressure and volume? You may not be getting the ful sufficiently to the injectors. Also, change your fuel filter if you haven't already. Is the check engine light on?
Thanks;

This happened to me recently on my 2004 Grand Cherokee. It stalled out three times in a month. No one came up with any codes except that my throttle sensor needed to be replaced ($80). After it was replaced, it stalled two more times, but this time the check engine light never came back on. My local Jeep mechanic looked it over for around six hours and could not find anything. However, my amps on my battery was half of what it should be. He stated that the computer may not have enough juice to control the throttle idle that activates when the vehicle is in low idle speeds. He also stated that once you remove the old battery to touch the battery cable terminals together (you can use a wrench if terminals won't touch) for around ten seconds. This is supposed to drain any remaning juice from the jeep and is supposed to reset the idle memory and computer for the vehicle. After replacing the battery, crank the Jeep up and let it run for at least five minutes without ever touching the gas pedal. Leave it to idle and I repeat, do not touch the gas during this time. The mechanic stated that letting the vehicle run for at least five minutes without touching the gas pedal will set the computer for the Jeep to run efficiently with the new battery and will also set the idle memory for the jeep. I did so and you could actually see the RPM's going up and down until the Jeep found an efficient idle setting. Try that, I know it sounds simple, but I tried every else before this, and it has not stalled out since a couple of weeks ago. I'll write back if it does before the end of next month. Hope this helps.
