Ok, well I just bought a 91 dakota. First day I got it, I had it stall on me once (automatic transmission). Now, it's been doing it almost every time I slow down or stop. It usually starts again right away, but sometimes I have to wait a few minutes. When it doesn't stall, it starts to lurch forward when I start going again. I'm pretty much retarded when it comes to anything mechanical, so I don't know where to start looking. Anybody have a similar problem before, and know what this might be?


-edit- When it stalls like this, my oil pressure drops. When it starts up again, it's fine.

 

well you're not in too bad of shape look for a vacuum leak for starters,also you may want to see if your CC is plugged up that can cause a stall...also since you're fuel injected change out the fuel filter and a tune up might be in order.as far as the oil pressure it will only read when the engine is running so don't worry there...

 

Also, it might sound odd, but check your transmission fluid level (engine warmed up and running, parked on level surface, and transmission in neutral).

Why I say this: well, I flushed my friends dads trucks transmission, and afterwords (I swear) I checked the transmission fluid level and (I swear) it checked good. Well, it would have a similar problem (when slowing down or stopping, it would like to "die" momentarily). This was on a 2004 GMC Savanna, FYI. Well, the fluid was check again a few days later, and sure enough, the fluid was barely registering on the dipstick. Filled her up, and she was good as can be. (My theory is, since the dipstick/filler tube on vans like the Savanna are [no kidding] about 3 feet long, there was still fluid in the line, distorting the reading on what the level actually was)

With that said, you will also want to check the catalytic convertor (if you hit it with a rubber mallet/hammer and it rattels, its bad; sometimes it will be bad and not rattle; a bad catalytic convertor can also cause lack of power).
Basically, yea, check everything boomer_87 said to check.
