supposed to say "red" tab in caption, and it can be cleaned

 

Looks like i am mistaken about that, I just found this from an expert:

A separate IAC motor is not used with the 5.7L V-8 engine. The IAC motor is not serviceable on the 5.7L V-8 engine.The throttle body is located on the intake manifold. Fuel does not enter the intake manifold through the throttle body. Fuel is sprayed into the manifold by the fuel injectors.

Filtered air from the air cleaner enters the intake manifold through the throttle body. The throttle body contains an air control passage controlled by an Idle Air Control (IAC) motor. The air control passage is used to supply air for idle conditions. A throttle valve (plate) is used to supply air for above idle conditions.

5.7L V-8 Engine:
The throttle body on the 5.7L engine is an electrically controlled unit. A mechanical cable is not used to connect the throttle body to the accelerator pedal. The accelerator pedal position sensor (APPS) along with inputs from other sensors sets the throttle blade to pre-determined positions.

Except 5.7L V-8 Engine:
Certain sensors are attached to the throttle body. The accelerator pedal cable, speed control cable and transmission control cable (when equipped) are connected to the throttle body linkage arm.

A (factory adjusted) set screw is used to mechanically limit the position of the throttle body throttle plate. Never attempt to adjust the engine idle speed using this screw. All idle speed functions are controlled by the PCM.

 

hmmm
well heres another thing that came up on the weekend. Going for a 7hr drive everything seems fine, getting great milege (computer 12.2l/100km) . check engine light comes on. Code P0404 - Exhaust Gas Recirculation Control Circuit Range/ Performance.
I just changed my EGR in November. That would be the second one in one year. Why is this on? Ive heard of an EGR solenoid. Where is this and can it be changed. Might this assist my stalling issues/.? still only when it is cold out.

 

this code does not affect anything else. just check engine light is on. Truck seems to run fine so issues. other than stalling once and awhile still

 

Did you ever find the cause of your stalling? Mine stalls occasionally when coming to a stop. As if the idle drops too low. Can keep from stalling by running A/C or defrost which seems to trick the PCM into setting the idle a little higher.

 

Well, unfortunatly it runs awesome during summer, never stalls. Just waiting for cooler temps. -11C this morning, usually around this temp and lower it likes to stall. Especially from reverse, brake and drive. combination of turning wheels and throttle all at right time. ONLY when its cold. Let me know if you find anything??

 

If yours only stalls when cold, have you tested you IAT sensor? It tells your PCM what the temp of the air coming in is and makes it adjust accordingly. If it is off that could be your problem. You can test with a multimeter and heat gun/hair dryer. Check youtube.

I just replaced my crankshaft position sensor and it seems to idle better. Haven't driven it enough yet to give the computer a chance to learn the difference, but hoping that it fixes my problem.

We shall see...

 

i have a 2006 ram hemi 5.7 vin2 and have been getting a p3400 error code. this thread has had more knowledgeable answers from people that actually know wth they are talking about then any i have read. my question is if i drive in tow mode will this eliminate my issue with the mds caused error code or will that cause more damage in the long run. have had this problem off and on for a few years and an oil change has allways fixed it, and yes i keep up with my oil change schedule. i am only 2 months and 1k miles after last oil change this time and the problem is more noticeably different then before maybe twice as much. i could replace the solenoid myself if that is the problem but it would take some time as i am not a mechanic and can not be without truck at this time. i am looking for a safe, quick and cheap fix at this point. thank you for any help with my problem.
