1996 Jeep Grand Cherokee stalls when brakes are applied
My Jeep has 78,000 miles, just had a brake job 4 weeks ago.
Starts from cold with no problems, but within 5 minutes, as soon as I brake to go around a corner, or come to a stop light, the engine dies, and is very hard to start again. It almost sounds like it is not getting fuel, but the fuel pump was replaced not too long ago. When it finally starts, it runs rough and sounds like it's coughing and sputtering before dying again! Oh, and this just started, like today, it's been fine.
Any ideas? Suggestions? Thanks so much for your help!
Re: 1996 Jeep Grand Cherokee stalls when brakes are...
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.

This is caused by by a bad ignition switch. According to the dealer the ignition switch contains an antenna that many of the sensors use to communicate with the vehicle, as well as the key fob. When the switch starts going bad the vehicle computer losses communication with these sensors and starts producing codes which include the 4wd and the electronic brakes. My fiance has had the same issues with her Grand Cherokee as well as the key fob not working, the remote start not working, the service engine light comes on, the door chime will sound when the key is NOT in the ignition and the lights are NOT on, as well as numerous codes usually relating to loss of communication with one system or another. All of which are fixed once the ignition switch is replaced. Unfortunately, this usually only fixes the problem for a short time (weeks or maybe a few months) before the piece of junk ignition switch fails again and it all starts over.
