SOURCE: IAC Valve Location - 1996 Jeep Grand Cherokee

The idle air control valve is located on the back of the throttle body. It has an oval electrical connector and two torx screws holding it in. Unplug the connector, remove the two screws then lightly tap the body with a soft faced mallet to loosen it from the body. 
Once you have it out and prior to installing a new valve clean the seat inside the throttle body where the idle control fits. This must be very clean! Installation is in the reverse order. 
 To save some cash, pull the valve out and clean it with throttle body cleaner, this usually fixes the problem for quite a while.
Good luck and hope this helps.

SOURCE: I'm looking for instructions to replace serpentine

You can check out the autozone.com website and register the vehicle. It's free and you will have access to an online repair manual for the vehicle. The steps for changing the belt and the routing diagram should be available there. Hope this helped and best wishes.

SOURCE: 1996 jepp grand cherokee 6 cyl. kepps stalling out

Have a code test done (most larger parts houses will read codes for free)
Get yourself either a haynes or chilton manual and look up any codes and find what they are related to. Manuals will also list individual tests to components that you can do using a decent multi-meter.
Most common cause of a problem such as yours is either a failing crank position sensor or fuel pump but it can be caused by many other items including a loose connection at the ignition switch, coil etc. (why testing is important) Wish there was something simple like a "stalling out switch" you could replace, but there isn't!
Good luck and post back if you have a specific question about an individual part or system!

I've cleaned the iac valve, changed the map and the spark plugs still get the spudder like its going to cut off . sometime it does. What else could be wrong?


It could have a clogged fuel filter or a failing fuel pump. Contaminated fuel, clogged injectors. Check for vacuum leaks.
Crankshaft position sensor failure is common on the 6 cyl grand cherokees.
