I have a 1998 Dodge Dakota 5.2L v8 and it stalls immediately in reverse and when coming to a stop. When coming to a stop the rpm falls to like 500 and tries to come back up then stalls. I replaced the IAC and it made it run better but didn't fix it. We took it to a shop and they hooked the computer up to it and said they couldn't find any sensors that were bad. Could it be a transmission problem? I am beginning to think so.

 

Sounds like a bad TPS sensor.

 

Mine was doing that a couple weeks ago and I just replaced the battery cable end completely took care of the problem. No code started good but had a stalling issue. Sometimes something that simple can be the culprit. Its worth a shot its cheap and easy

 

Any more ideas on what this could be? How do you test the TPS and the crank position sensor?

 

I finally fixed it. I ended up having to replace the CPS and that fixed reverse and I replaced the TPS and that fixed the stalling while driving.

 

All's well that ends well!
