Went out to start my Aspen and it started then died right away.Got out opened my gas cap and retightend it and tried to start it 3-4 more times, same result. So this time I pushed on the peddle and kept about 800 rpm and it did not dy until I let it idle. Repeated 2-3 more times, same result. Have plenty of battery because I can crank & crank,
not a battery issue. Drove it too my dealer died every time I stop or idled,util I got to the service garage then it would stay running. Said they could not find anything wrong.Did the same thing back in 08 or 09 could not get anwser on what is going on . Could the fuel system need recalibrated.

    It is possible that a dirty throttle body may be the cause. 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.

    Is there gaskets or seals to be replaced after cleaning?
