I had the same problem... frustrating.

I picked up a repair manual at the parts store. I took off the throttle body and cleaned it with throttle body cleaner spray. I changed the Idle Air Control Valve (idle speed motor) which was very clogged. While I had the throttle body off I also changed the Map Sensor and Throttle Position Sensor. The manual will walk you through the steps. I had never done anything like this before. If I can do you so can you.
My Jeep has never run better. Good Luck

it sounds like your automatic transmission quit his job. How much miles are on the clock? If more than 150.000 and you pulled trailers, climb mountains etc. this will be the first choice. Let the engine idle, push the brakes and check if the car will go in any gear. If this will happen only in reverse gear, your auto trans need to be replaces. You can use a rebuilt auto trans.

Since the car stall only in the drive position, it sounds(i'm not there to actually ck the car)like when the engine torques, it might be pulling on a harness somewhere and killing the ignition. Do this,start the car and under the hood while the engine is running, move or jiggle the harnesses around and see if the car stalls. If the car stalls try to pinpoint the location on the harness and look for frayed or broken wires.

Put the key in the ignition and turn it on and off (3) times without starting the jeep, leaving it in the on position count the (1) flashing indicator Light, Eg: (5) flashes, Then there will be a pause, then it may flash (3) times, this is a code #53. Keep your Eye on them and write them down. If you should miss (1) Repeat as many times as needed, Info: A #55 means there are no codes!!

Check fuel filter . You have a mechanical pump & a carburetor on that model dont you?...Check fuel pressure (should be around 6-7 lbs) and check coil immediately after it shuts down...sometimes coils will act like that just before they go bad..

1996 Jeep Grand Cherokee stalls when brakes are applied


My 2000 Grand Cherokee had the same problem, without all the sputtering, it would just die approaching a stop. We could only keep it running by slightly pushing down on the gas petal when coming to a stop. I replaced the Throttle Position Sensor, but that didn't change anything. A new mechanic I found replaced the Idle Air Control Valve, and we've had no problems in a week.
