    after reading all the post mines does the same thing, i have notice though in the morning or when the engine is cool, it runs normal. It seem as if its running perfect, i just put a complete exhaust and eliminated cats. once the car heats up, the car shakes, and the engine light flashes and dings, i change all spark plugs, O2 sensors. Map sensor as well, i notice the gas pedal, would go to the floor with no reaction, as well then all of a sudden it would take off, but sputter, i checked all injectors they are all firing, and spark is on all coils with the same results,Today it cut off on me, in the middle of the intersection, unsure what it is with car, but really hating this issues, its going to the dealership tomorrow morning. once they diagnose it.
    - could someone tell me what does heater circuit control B- was one of the codes that stood out to me. as well.

    I might not be much help here but if the problems persist after changing several components, including the PCM, the problem might be in the wiring harness somewhere. Did the symptoms show up after engine mods or "repair". I have encountered times where someone did a "repair" and ended up pinching wires, the vehicle would stall occasionally when warmed up because the wires that got pinched were shorting.

    If the communications error codes or low voltage symptom is occurring even after an alternator and pcm replacement, wiring harness is where I would look for the problem. The voltage regulator is in the PCM, highly unlikely you got several bad ones.

    I've had a intermitant low voltage problem for the last 4-5 weeks. I changed the alternator first, then the battery. I still get 11.3 or so volts sometimes then it'll shoot up to 14 after a few miles. I'm going to check all the plugs and connectors really well, but what is the part number for the ambient air temp sensor, and how much does it cost. If it's a cheap part I'll give it a shot. thank you,

    Is that the sensor that bolts to the bumper under the fascia? Or is it the sensor in the air inlet tube next to the TB?

    my in dash outside temp display seems to be accurate, so I'm guessing my ambient air temp sensor is functioning properly?

    i had this same issues, my car would stall, and at stop lights idle very rough sometimes cut off.
    - turns out my PCM was bad, just got my car back, change spark plugs, 02 sensors, and change the oil.
    - i would say if you have all the original parts on the car put them back on there and drop it off at a dodge dealership,
    - because your PCM maybe bad, and mines was throwing 14 codes, and turns out nothing was wrong with it, but the pcm

    My 06 Magnum has been having all the same issues as everyone is describing. The issue is intermittent and after trying several fixes, I took it to the dealership six weeks ago. They couldn't get it to stall, so I took it back with a recorder to record when it does stall. It took a few days, but they came back to pick it up. After a week, they said they thought it might be the PCM, then after the weekend, the shop foreman told me it's the torque converter and said I need to replace/rebuild the tranny. He said that the PCM is fine after all. I don't see how the torque converter would cause the kind of random intermittent stall I'm getting. Because this is their diagnosis, I am planning on going over to have them show me all the info that was recorded over the past week. If I don't agree with the diagnosis, I think I'm back to square one. no fix. Has anyone heard of the torque converter causing what these cars are doing? I've posted threads about this, and am just looking for additional info before picking up my car and taking it to a tranny shop.

    Any follow up on this, anybody? Mine's doing the same thing.

    I have two somewhat modified Hemi vehicles with the NAG1 transmissions and, IMO, yes, the torque converter can cause stalling. I think it may have something to do with the TCC clutch operation. Both of mine, when warmed up and when coming to a stop will "dip the idle" to just above 500 RPM and then, most of the time, will go back up to normal idle speed. I can take either vehicle out of gear while coming to a stop and put it back in gear once stopped and it won't happen. After stopping, I can also take it out of gear and then put it back in gear and the RPM will go back to normal. I've also found that, sometimes, I can turn the A/C on and off and the RPM will go back up. This is probably because the idle RPM with the A/C on is probably set a little differently than without it on. I've tinkered with the settings a little using my HPT but haven't quite figured it out yet....but I think I am getting close. There are idle speed settings for both "Transmission Based Setpoint" and "Automatic Transmission" which, coupled with TCC slip %ages may all be connected somehow.

    Also, as a side note, I have another Hemi vehicle (Jeep GCO) that is modded almost exactly the same as the other two except it has the 545RFE transmission. I don't have this issue with it, so that tells me that it is most likely something in the transmission.

    Unlikely the TC lock-up circuit.

    Commanded idle values are different whether in P, R, or N. A/C engagement - again differing commanded idle depending on ambient temps and gear selected.

    It always amazes me how people will write a blank check to an independent shop in a heartbeat to shotgun part after part after part at their car. Then, when they’ve run out of ideas, throw up their hands and say “take it to the dealer” now that we’ve taken all of your money! Then this same person will expect the “stealership” to diagnose/fix it for free or at the least a greatly reduced rate because the other place already took all of their money and think the independent shop is the greatest thing since canned bear!

    Anyway, you might want to look at the plug to the throttle body. I’ve had more than one, including my own, that was doing the same thing. The ones I’ve replaced them on, including my own, haven’t had this issue since. However, this information is coming from a 15+ year Chrysler “stealership” service advisor. So be very skeptical!
