Question about 2004 Dodge Ram 1500

Stalls at idle

My 2004 dodge ram 1500 5.7L hemi with automatic transmission is stalling when idling at a stop light, etc. I had had my truck in at the dealership where they performed SB18-013-05 and the problem had been fixed but now it's returned. It presently has 2 active DTC's : P0406 and P0137. I read that there is an EGR replacement covered by emissions warranty and is also accompanied by SB18-010-04. This may be the cause of the P0406 DTC but is this also what is causing the revs to drop and stall?

    Took my truck to the dealership. A code was set for a vehicle speed sensor whenever stalling occurred. Mechanic followed troubleshooting procedures but found outcome to be pcm replacement. He then contacted engineering at dodge and found that there are two vehicle speed sensors which readings are taken from: one on the front left wheel and the other at the differential. When sensor on wheel was disconnected, truck would not stall. For some reason (engineering doesn't even know), engine light does not appear and truck runs well!! Thanks for your help.

    My trucks rpms drop below 500 when sitting at idle, then the truck dies. I can cut the ignition off, restart, and be fine until I idle again. Any clue as o how much this is going to cost me? I'm hoping there is a simple answer!

Check/clean the MAP sensor and throttle position sensor. This should fix the issue. Its a common problem with Chrysler products.

Idled high, replace IAC and PCV, now idles low and stalls


On modern day cars the parts that get fitted need to be adapted to the ECM using a decent diagnostic machine. I bet that this was not done and the car is now suffering as a result.
Something to try is resetting the ECU, simply disconnect battery for 10 minutes, reconnect, then start car from cold *without touching gas pedal* and leave idling until the rad fan comes on (this resets all the base idle settings) then take it for a drive - hopefully will solve the problem

03 dodge ram 1500 hesitates and tries to stall when in drive at stop sign or light.The tachometer fluctuates up then down hesitates then stalls.


Remove IAC (idle speed control) motor, clean with throttlebody spray cleaner & the port (hole)it came out of. Re-install & try it. If it cures it for a while & does it again, replace the IAC motor.

2004 ram 5.7, stalls when going up an incline


I had this same problem in my 04' Hemi I would be driving and as I pulled up to a stop sign or light it would die. No check light or codes. Took it to the dealer they said it was the alternator put a new one in and never had another problem.

Stalling problem when coming to a stop


Do you know what your AIS motor (automatic idle speed) is on your throttle body.Usually held on with torx screws 2 or 3. Thses are pretty well known for gumming up & sticking. It adjusts your idle automatically under load etc. If your take it off, spray it with throttle body cleaner & be sure to spray some in the port (hole it came out of) before you re-assemble it. Sometimes this will cure it or at least improve it enough that you know your in the right area, if replacement part needed.

Car will idle but stalls when its put in any gear automatic transmision


It's probably a bad torque converter---that's what allows the engine to idle when transmission is still in gear. It locks when the car is moving, but if it doesnt unlock then the engine will stall out.
