Check all the vacuum hoses on the intake manifold for a leak. Replace all broken and cracked lines. Check from the coil to spark plug wires with an inline spark tester for fire. Check the spark plugs for fouling and cracked terminals. Inspect the spark plug wires for worn or cracks. If you can check the fuel pressure to the throttle body. Also look at the air filter. Hope this will help you.

My 1998 Jeep Grand Cherokee Laredo turns off suddenly when stopped, and sometimes kicks when running. I'm wondering if it has to do with the fuel filter.
On my dodge truck, it was the throttle position sensor that went bad. It is located on the side of the throttle body. $50 for a new one, or $100 to have a shop do it.

Where is the Intake Air Temperature Sensor or the (IAT)Sensor on a 2004 JEEP GRAND CHEROKEE LAREDO 4.0 .??? I Have A Boss Performance chip that i would like to install....Thank's..
The air temperature is taken between the air filter and the throttle body. Look in the roof of your air cleaner box. (usually 2-pin plug) After the air cleaner, the tube that sends the air to the throttle body has the mass air flow sensor in it.(usually 4-pin plug)

Abrupt stall
Take air intake duct off at throttle body and spray WD-40 into throttle body with plate open, then try to start, if it fires up for a second, then dies, it's a fuel delivery problem.
