 Subject: V6 stalls when cold
IP: Logged
Message:
I have a 2000 Dakota 3.9L V6 auto 4x4. When it is cold the truck start right up but stalls and within a couple of seconds . It will start right up again and do the same thing. If I keep my foot on the gas it idles smoothly but, I must keep it above 1200 rpm. If I take the truck around the block when it is doing this (1 foot gas, 1 foot brake) and I come to a stop it will be fine and idle at around 800 (about normal). This does not happen every morning but the colder it gets (<30f) the more likely it will happen. What is the deal?

My truck has done this a few times since I have had it. Everytime it has been the IAC sensor just needs to be cleaned up. It is located on the back side of the trottlebody. I just take off the whole throttlebody and clean up the whole thing when I do it. I dont know if you have a V8 throttlebody on it or not, but ever since I put one on mine I have had to clean it more often. Try to clean it up and if that doesn't work try replacing the sensor.

What do you use to clean this sensor? I have a 2002 3.9L Dakota Quad Cab, and it'll die sometimes when I'm in reverse and have to step on it a bit, like reversin uphill. Do you think this could be caused by the IAC as well?

Thye IAC is not a sensor but a pluger controled
by a elec motor moving it back and forth, open
and close to adjust the air flow for idle.
It is told what to do by the comp from the signals
it recieves from the IAT Engine temp and idle
speed, those 2 sensors also controle the injector
pulse when cold in open loop. will add more fuel
to compensate for the cold motor
