I'm looking for a little help on where to start with this problem. I have a '93 Dakota V6 Magnum 3.9 that will start fine, but if it hasn't been run for a couple of days or is cold will start to chug-a-lug along (sputter, pop) when you get to about 25mph. When slowing or stopping (taking foot off of the accelerator) it will stall. Some times it will run fine after stalling and others, this scenario will repeat several times before it runs fine. Fuel pump was replace about a year ago (to include fuel filter). I checked the engine codes and don't have any (just get 55).

Please point me in an appropriate direction....thanks.

 

buy a tank of supreme and add a can of B-12 chem tool to the tank, also a tune up wouldnt hurt either. get an additional can of b-12 and add that to the oil, run for 5 min and drain, that should help out
