Question about 1999 Jeep Grand Cherokee
This happened to me recently on my 2004 Grand Cherokee. It stalled out three times in a month. No one came up with any codes except that my throttle sensor needed to be replaced ($80). After it was replaced, it stalled two more times, but this time the check engine light never came back on. My local Jeep mechanic looked it over for around six hours and could not find anything. However, my amps on my battery was half of what it should be. He stated that the computer may not have enough juice to control the throttle idle that activates when the vehicle is in low idle speeds. He also stated that once you remove the old battery to touch the battery cable terminals together (you can use a wrench if terminals won't touch) for around ten seconds. This is supposed to drain any remaning juice from the jeep and is supposed to reset the idle memory and computer for the vehicle. After replacing the battery, crank the Jeep up and let it run for at least five minutes without ever touching the gas pedal. Leave it to idle and I repeat, do not touch the gas during this time. The mechanic stated that letting the vehicle run for at least five minutes without touching the gas pedal will set the computer for the Jeep to run efficiently with the new battery and will also set the idle memory for the jeep. I did so and you could actually see the RPM's going up and down until the Jeep found an efficient idle setting. Try that, I know it sounds simple, but I tried every else before this, and it has not stalled out since a couple of weeks ago. I'll write back if it does before the end of next month. Hope this helps.

What would make the computer go bad on a 2004 jeep Cherokee? The check engine light came on and had the throttle sensor and crank sensor changed.
