Answer 1
Chrysler ecm's tend to "forget" idle air control motor positioning when the battery voltage drops below 10 volts. If your battery voltage drops below 10 volts during start then the ecm will lose it's memory on that position. The problem most likely revolves around why is it starting "weak" maybe the battery has lost some capacity, maybe the starter is drawing too much, maybe battery cables are too corroded internally causing too high a voltage drop during cranking, maybe the alternator isn't charging the battery sufficiently, maybe there is a parasitic load on battery after you shut it off draining some of the battery capacity. Good luck! -

I am having the same problem on my 1998 5.2L dodge dakota. My truck will start when jumped by another, and it will run as long as I am on the gas and it is still connected by the jumper cables to the other car. It will, however, shut off as soon as I let off the gas. Does that narrow it down to the alternator? -

It's your battery connections or battery clean them real good clean posts... Your alternator won't work if u start your truck an pull one of the wires off probably negative wire pull it off if.ur.truck is still running.then alternator is doing its job -
