Not really sure what causes my truck to stall when coming to stop for no reason. No check engine light at all. It dies and then I have to restart it and hope that I can make it through the next light without it dying again. Last mechanic said he could find nothing, someone has to know what I am referring to?

    Throttle Body Service
    The throttle plate and bore may become coated with contaminates from the intake system. This will restrict the air flow past the throttle plate when the throttle is closed. The Idle Air Control Motor (IAC) may not be able to compensate fast enough to keep the engine at the target idle speed and stalling occurs. If the throttle body plate and bore are coated with contaminates, perform the Cleaning procedure. You will need 04897156AA Mopar Throttle Body Cleaner, Scotch Brite Pad, (Green) or soft Bristle Brush. Remove the throttle body from the engine. Spray the entire throttle body bore and both sides of the throttle plate with Mopar Throttle Body Cleaner, p/n 04897156AA. This will remove the bulk of the contaminant.
    CAUTION: This cleaner should only be used in a well ventilated area. Do not allow
    contact with skin or eyes. Rubber or butyl gloves and safety glasses are
    recommended. Wash thoroughly after use. Do not ingest.
    NOTE: Use only Mopar Throttle Body Cleaner, the use of other cleaning agents may damage components of the throttle body.
    While holding the throttle open, use a small, (1” x 1”) piece of green Scotch Brite scuff
    pad, (or soft bristle brush), clean the throttle body bore and throttle plate, (including
    edges).
    NOTE: It is important that this cleaning procedure be performed thoroughly and
    completely. The edge of the throttle plate, and the portion of the throttle body
    bore where the throttle plate comes to rest are the most critical areas where
    the cleaning should be concentrated. These areas must be free of all
    deposits when the cleaning is completed.
    Thoroughly clean the throttle body with Mopar Throttle Body Cleaner, p/n
    04897156AA, and blow dry with compressed air. Inspect for any foreign material
    which may have been left from the cleaning process.
    CAUTION: Do not blow shop air pressure directly into the throttle shaft or throttle
    body housing holes.

    I had the same problem, I replaced plugs and wires, replaced EGR valve, took throttle body off and cleaned it. On the Ram 1500's the ICV is built into the throttle body, after all this it still was stalling and now running rough and using a lot of fuel. Took it to a well known mechanic and he solved the problem, First both my upper 02 sensors where bad, And he also told me that the throttle body/ICV are electronic so as the throttle body gets build up in it with time, the computer keeps compensating for this. Well when I took it apart and cleaned it and put it back on, it confused the computer and truck wouldn't run very well, so my mechanic had to reset my throttle body/ICV. Truck runs like a top now. Hope this helps...
