My engine stalls at idle why?

The engine shut off when its put in gear

Keeps shutting off after starting.

I had already tried that and it didn't work.

I solved the problem. I took out the fuel pump relay and the fuse first. Then I opened my gas cap and turned my ignition switch on but not try to start it. I put fuse and relay back and waited a few minutes. Then I started it. It worked. So far it's doing great. Thanks so much for all your help. It has been greatly appreciated!

My battery was dead so I jumped car. Charged battery up because it is dead but will not be able to replace for another day or so. I work at a diesel shop but cars sometimes trick me. It was idling high at about 1000 rpm it is uaully about 650 I belive. When the AC is running it runs a little high but drops down every now and then. With AC not running it will keep jumping up and down but gets weaker every time it jumps down and will shut off. My alt was reading about 13.5 to 14. Not too sure!

Thanks !

I drive a 1999 Dodge Durango. Had the transmission rebuilt and now after the car heats up and is driven a few miles, it begins to run rough and when going to stop the engine starts cutting out like it wants to stall, and once you actually stop, the engine picks back up but still runs rough. I am not sure what to do, I have replaced the crank shaft position sensor, fuel pump, oxygen sensor, ECU, and tested the throttle position sensor, air intake temperature sensor, MAP sensor and all are in working order. The trucks engine also tries to cut out even if you manual downshift through the gears. Any advice would be nice I cant stand this anymore

I have never did a timing belt, I am pretty sure mine has a timing chain though. When my vehicle goes into limp mode, it runs better, but as soon as I reset the computer it goes back into trying to stall. I recently had my tranny rebuilt, is it possible there was a vacuum line left off?

I have scanned it I have my own scan tool. I have oxygen sensor circuit low, and fuel system lean. I have replaced the 02 sensors and am still getting the codes. Runs fine while codes are on, but once reset the truck runs like crap

My battery died, car started with a jump but won't stay running at idle, only runs at higher revs (1000rmp or higher). It starts now without a jump but still dies at idle speed.
