I was having sporatic stalling of my 2002 Dakota, 4.7. It happens when it is cold, It starts fine, then I drive about 100-200 ft, stop at an intersection, then when I go to accelerate, it sputters and stalls, .It takes a short time to re-start, but starts like it has been flooded. I brought it to my mechanic and all he could suggest is that the battery reserve under a load was not enough, he said that it tested at 300 amps when it should test out at 350-375 amps. He said when this happens the computer screws up (like when you disconnect the battery), and the memory does not tell the computer how to run. Then it comes back.
After it stalls I run it down the street and it seems fine. Like i said only when it is cold.
He suggest a new battery. How long should these batterys last, I have 67,000 miles on it.
Thanks, Barry

 

its due for a new one...get a optima far better than stock well worth the money...

 

How much do those go for??
So, is that a common problem that would cause the stall

 

Very good possibility, go to your nearest INTERSTATE retailer www.interstate.com they will check your exsisting battery first..if bad they will put the new one go with the red top optima part# RED75/35 proaly around 125 bucks but they last for like 10 years

 

Ok i dont see how this could be a battery problem. After your truck has started your alternator supplies ALL the power to your truck plus charges the battery. In an even where lets say your amp uses up all the alternator current then it would draw from the battery. It sounds more like a fuel problem then anything. Check your fuel pressure.

 

When my battery went bad and i got it started, it only ran when i held the gas down. When i let off, it stalled. Put a new battery in it and it stayed running.

 

It is most likely the battery. Any Auto Zone or Pep Boy ect. will test it for free.

 

Plus when they test your battery they will also test the alternator too...

 

If your truck dies its not because of the battery its because of the alternator. If it stays running with a new battery then obviously you need a new alternator.

The only job your battery does is start your truck, after that its useless, you can take it right out of the truck while its running and the truck wont die or even flinch. So if you say that your truck would die with your old battery, but wouldnt with your new battery, its the alternator. The alternator has problably worn to the point where its output voltage and current isnt enough to provide the nessicary spark to the engine at idle. But when you rev up the engine the alternator turns faster providing more voltage and current. When you put your new battery it was compensating for the lack of current from the alternator. Eventually your battery will die. Hope that makes sense to you.

 

that is not true, my moms durango with the 4.7 v8 in it did the same thing that he is describing when the battery went bad, all we did was replace the battery and it has been fine ever since, it has been almost 2 years now
