My cherokee starts ok and idles for 30-60 seconds them it starts acting like its gona stall then idle ok again, It also acts like it missing when you try to rev it up once u get it reved up it runs ok

Seen this many times on Grand Cherokees. The crank sensor is going bad. Replace it with a dealer crank sensor, not an aftermarket one.

I'm assuming you mean a coolant temp sensor. The sensor tells the computer what the coolant temp is.
Normally when a sensor fails the check engine light comes on to warn the driver. Normally but not always.
One thing that could affect both problems you describe is the idle air control valve. If the valve fails or sticks, the engine can stall or have a high idle speed. The computer controls idle speed by how much air is allowed into the throttle body.
The throttle body could also be very dirty.

You have a bad idle air / idle sensor. Your car believes that you are in idle at all times so when you come to a stop the engine floods. When the fuel evaporates you can drive again. Drove me crazy when it happened to me.

It appears that the fuel pump might be going bad. To eliminate this possible cause, have the pump output pressure tested by a mechanic. It is located in the tank. The pressure test can be done in about 1/2 hour at a good garage.The fuel pump replacement, a four hour job, costs ~$500.00.

tune up plugs wires fuel filter could be a idle air control valve throttle position sensor is the check engine light comeing on to no for sure have the vehicle tested by a trusted mechanic

your carburetor should have a fuel filter in the carburetor body where the
fuel line enters it replace it and, any other in-line fuel filter the engine might have

make sure your idle air control motor is working, if you give and hold gas pedal a little will it stay running in drive.

have you ever had the injectors checked. if not try runing some fuel injection cleaners through it and see if that works

Sounds like a bad IAC (idle air control valve/sensor) that controls your idle when going from throttle to idle. If bad your idle will act crazy and can cause stalls easily. Pretty sure that's it.

Has the check engine light been coming on ? Mine did, I check and it was showing The oxigen sensor too lean they try to sell me all o2 sensors but I check the fuel preassure and it was not ok only ocassionaly so if your fuel pump is not bringing the proper volume or correct preassure to the engine is gona show as a lean code letting u know somenthing is wrong but it was created by a defective f/pump do not start dumping money in sensors because 1 sensor can go bad but not 4 at the same time , ussually when this happens is a mechanical problem that can not be detected by the computer and is the only way to show u there is something wrong...If gona buy f/pump do not install other than AC delco brand becouse thats made for GM pruduct like your Escalade. If u dont have a check engine light on next simptoms will be ..If idle for long time it will act up and when you get it going it will miss and shake for a while untill u drive steady for couple of miles then it goes away,also if you are going down the road and u here the engine backfire (noise coming from the air filter) it means is running lean wich its created by a faulty f/pump.Good luck and let me know the outcome...
