Why stalling out and jumping when accelerating?

Could be several things, weak fuel pump (failing), , or fuel pressure regulator ,Often, the engine will stall out during a fast accelerating, or suddenly jump and accelerate more quickly than you intended. It also might take more effort than usual to get your car to accelerate, and when it does, the acceleration will happen much more slowly than normally. if you have bad plugs or wires. good-day!

CHECK ELECTRONIC COILS AT PLUGS!

sure soundz like u mite b on the right trac...chek ignition timin...

Plugs ,wires,coils.

when was the last good tune up done? fuel filter changed? air cleaner? check emissions vacuum system for leaks..repost findings

Most likely cause is spark plug wires shorting out under load. Loose, or damaged.

replace the battery, on a dodge when battery is weak the idle air control solenoid tries to search for the right position. and will keep stalling sometimes wont stay running.

If it's a 7.3 deisel, your timing could have jumped one tooth or your injector pump slipped one way or another. Pull your pump, lines and gear and engrave a line straight up from the timing mark so you can see it when you reset the timing gear.

I just went through lots of troubleshooting and expense on my 1996. Whenever I would lift my foot off the accelerator and was below about 30 mph, the rpm's would starts jumping around and sometimes it would stall. If I gave it a little gas (accelerator), I could sometimes keep it running. It also backfired once in a while. Starts right back up. Also, if I let it idle while in part, it would die after 1-2 minutes.

I ended up finding a hole in the fuel regulator. About a ~$70 part if you get an AC Delco, but very simple to change.
