ok, so my 02' durango was running perfect!!! until a few months ago it started stalling when i come to a stop, when giving it gas or driving it runs awesome!!! but i stop it sputters down and dies. I replaced the TPS and it didnt do anything, i took it to a shop and and they looked at it, (keep in mind there is no CEL on) they said after hooking it up, they found that the IACV was slow to respond. so i replaced that and it seemed to run good for that day. the following day is would sputter but not die, than so on and so on. finally, to today it is dying again. i dont know dodge's very well at all... im more of an import guy, and this is really getting to me. i have a long trip coming up and need to get it fixed. anyone have any idea's? im lost!!!!


past issues include o2 sensors going bad, those are all replaced. fresh tune up about 9 months ago. tps and iacv were both replaced. still having trouble...

 

Do you have a 5.9L engine or 4.7L?

 

4.7l!

 

You are going to think that i am nuts. Unplug the clockspring. The clockspring ground circuit is also for the pcm, tps, asd relay and fuel pump. Also look under the dash and ck the large connector. On the early durango's the connector pins would turn green.Ck them a clean if needed.

 

the large connector is the one that a scan tool would plug into correct? what is the clockspring? and where can i find it? once its unplugged how long do i keep it unplugged? any more info i need to know about the clockspring as far as getting this all reset?

thanks again for the help i appreciate it so much!!!

 

also i keep reading other posts simular to my problem and i see alot of people are suggesting the battery... can a bad battery really cause the vehicle to stall at stops... wouldnt the battery light be on or no?

 

no, i have never seen a battery light on these trucks, but the pcm is extremely sensitive if the battery voltage drops under 12v so if it is 4 years old or more i would just replace to be save

 

You can try to clean the connections and have the battery load tested.


The clock spring is in the column under the drivers side air bag in the steering wheel.

 

update*** thanks for all the replies! i just finished cleaning the throttle body, bottery connection, and even pulled out the IACV again to clean inside there to be sure there was no carbon build up.... after doing all this the vehicle still stalls at stops. the battery is less than a year old!

would resetting the PCM help? how am i supposed to reset it? thanks

 

Tried this yet?
