I have created a couple of forums about this problem but still haven't fixed it. My 98 Dakota 5.2l has a stalling problem. I put a remanufactured motor in it and it had a stalling problem. Replaced the CPS, TPS, and IAC. It ran good for two months and now it is back.

It will idle in park and you can rev it up and it will recover and stay running. When driving it will recover sometimes and stall others. When it stall it wont idle in neutral when you start it back up. You have to give it gas to start it and to keep it running.

Any thoughts on what it could be? Any help would be appriciated

 

Was the reman motor newly remanufactured or did it have some miles on it? Is it throwing any codes? Sounds like an intake/fuel related problem...

 

I'd be suspect of PCM or IAC. Latter more than the former.

 

Hows you batt and alt. These trucks are very picky when it comes to the amount of power. I had a similar problem when starting my truck the neg cable was loose and had to use the pedal to idle for a little bit. Will it come back after a few min or what?

 

Have you checked for vacuum leaks?

 

I had this happen once while idling in line at the dump right after I bought my truck. I tried to ignore it because I was in denial and didn't want something to be wrong already.

I took apart the throttle body and it was filthy...Cleaned it with carb cleaner and it's been fine since.

1 - Clean the throttle body & sensors.
2 - New air filter.
3 - Pour a bottle of fuel injector cleaner in your tank.
4 - My PCV valve was broken...I replaced it. I have no idea if there's a related issue or not?

 

Maybe worth a read - Link

 

Newly remanufactured and is not throwing any codes

 

Put a new battery in it right before this happened. I don't know about the alternator

 

I have tried spraying carb cleaner on lines but that's about it.

I have ran fuel injector cleaner through it but have not took the throttle body off to clean it. I guess that needs to be the next thing i do. It has a new air filter. My PCV valve does make a hissing/rattling sound and i have replaced it twice and it the sound always comes back.
