battery died - got jumped, it started and now stalls when at idle

OK, it may just be the battery, but I did do a full recharge.

I have my fuse out of the warning beep for my interior lights and this also controls the warning for headlights (not a smart thing on my part).

I left the lights on drained the battery, got a jump and it started right up. Now it runs fine except it stalls while waiting at a light/stop sign or when ever it is just in idle mode. It starts right back up again.

Any other ideas? I do not think jumping it would have fried anything.

Thanks
Dave

It just needs to relearn after charging the battery, Start it up and hold the accelerator pedal down slightly (Like 900-1000 RPM's) after a little while let off it should idle,If your throttle body is really dirty pick up a can of Air Intake Cleaner (Aerosol) & use a old tooth brush & clean the throttle body

It's probably the IAC (Idle Air Control). I had the same thing happen 4 days ago. The throttle body was dirty and the IAC "slot" is in there. I didn't know exactly what it was so took it to the dealer since it could be several things wrong and I didn't want to chase and install parts. They cleaned the throttle body and that fixed it. It won't idle because the IAC lost it's memory. When that happens idle it around 1000rpms and it will relearn what it's suppose to do.

See the diagram in this thread:

This happened to me. I left the dome light on overnight, and it was stone dead in the morning. I was able to jump it to get it started again, but as you noted, I had to keep the RPM up for about half of my drive to work (about 10 minutes) or else it would try to stall again. By the time I pulled into the parking lot at work, it seemed to be working normally. When I went to go home at the end of the day, it would not start at all, despite plenty of charge, and many repeated attempts. It was throwing a code, so I called the service dept. at the Jeep dealer and had them look it up (I carry a xerox of all the error codes now), and it turned out to be my old friend, the camshaft position sensor. I decided to make another attempt at starting it, and to my surprise it started, but once I got it home I did not try to drive it again until I changed out that sensor.

Have you recharged the battery? When a battery is discharged the alternator won't adequately recharge it. Put the battery on a charger. Once the battery has a proper charge on it, have it load tested.

With our "electronic" vehicles, the first step in just about any electrical trouble shooting is to check the condition of the battery.

Keep in mind that free advice can frequently be worth less than you pay for it.

Thanks....

I tried the easiest suggestion and it worked. Started it and put a case of soda on the gas peddle to keep the idle around 2000. Worked perfect, no more issues.


Thanks a lot for the assistance.

Happened to me also - left the lights on w/ the fuse removed.


The battery would not charge after being jumped. Put it on a trickle charge for 24 hours and was good to go again. But it would stall and idle rough for a while. Also, the engine did not want to start one time: cranked and cranked and cranked. When it finally started it felt like it was an old carb'd rig as it was flooded and needed to be cleared through. After a day or so of this weird behavoir the Jeep settled down to normal.
