My '98 Dodge 2500 w/5.9 V8 GAS!, will start but stall instantly. I can keep it running by giving it gas but once I let off the pedal it stalls. Smells really rich. It's not flashing any codes.

Any ideas????

 

mine does the same thing but only when its really cold until it warms up a little bit, havnt figured out why yet

 

Start by cleaning the IAC, disconnect negative battery cable before doing so. https://dodgeforum.com/forum/dodge-r...n-the-iac.html

 

Also havr your battery and alt tested. Minr did the same thing and it turned out to be a bad cell and weak alt. The pcm will do crazy things when its not getting enough voltage

 

Well I cleaned the IAC. It was filthy. But it still does the same thing. I did forget to take off the negative cable! Things happen when your 4 year old son is helping. Will that make a difference?

When I keep my foot on it, it runs but smells like it's loading up. It's been smelling rich for the last couple of weeks. O2 sensor???

UPDATE!!!

I pulled the battery cable off and it must have reset something 'cause it runs!!!!!!!!!!!!!!! Thanks everyone!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
