above, record them on the repair order and repair as necessary before proceeding further with
Inspect the air induction system including the air filter element, resonator,
air induction hoses

|1.||Remove the throttle body from the intake manifold. Refer to the service
available in TechCONNECT or the Ram Truck service manual (publication no.
81-370-04059), Section 14 Fuel Injection, Throttle Body, Removal, page 14-36.
|CAUTION: Use only Mopar Brake Parts Cleaner, p/n 04897150AB
or 04897151AB, as
the use of other cleaners may damage components of the throttle body.
Use this cleaner only in a well ventilated area. Do not let this cleaner come
in contact with the skin. Rubber or butyl gloves are recommended. Wash
thoroughly after use. Avoid eye contact. Avoid ingesting.
|2.||While holding the throttle open, spray the throttle body bore with Mopar
Cleaner, p/n 04897150AB or 04897151AB. Spray the entire throttle body bore and the
manifold side of the throttle plate.
|3.||Use a soft cloth to help break loose deposits to clean the throttle body
bore and throttle
plate. While holding the throttle open, clean both the top and bottom of the throttle body
bore. Also clean the manifold side and edges of the throttle plate.
|NOTE: Take due care not to scratch, bend, or dent throttle
plate and/or throttle body
|NOTE: It is important this cleaning operation be performed
thoroughly and completely.
The edge of the throttle plate and the portion of the throttle body bore that is in
the closest proximity to the closed throttle plate is the most critical area where
the cleaning should be concentrated. This area must be free of all deposits
when the cleaning is completed.
|4.||Spray the throttle body with, Mopar Brake Parts Cleaner, p/n 04897150AB
04897151AB, and then blow dry with compressed shop air. Inspect for any foreign
material which may have been left behind during the cleaning process.
|CAUTION: Do not apply shop air pressure directly into the
throttle shaft and throttle
body housing holes.
|5.||Open and close the throttle plate on the throttle body to verify that
there is no increased
effort when moving from the closed position. If the condition is corrected, proceed to the
next step. If the increased effort still exists, then some other condition exists with the
throttle body and further diagnosis and repair will be necessary and will not be covered
by this repair procedure.
|6.||Install the throttle body on the intake manifold.|
|7.||Open and close the throttle to verify that there is no increased effort
when moving from
the closed throttle position. If the condition is corrected, proceed to the next step. If the
increased effort still exists, then some other condition exists with the throttle linkage and
further diagnosis and repair will be necessary.
