  Q: How to Remove and Install a Throttle Body Without Altering Engine Idle Speed on Dodge Ram 3500?

  A:

  The throttle body comes with a set screw from the factory that controls how far the throttle plate can open and this screw should never be adjusted during idle speed adjustments, because the idle speed is handled by the PCM. Removal starts with air cleaner removal, then unplug the electrical wires at the MAP Sensor, IAC motor and TPS. After that, pull off the vacuum line at the throttle body and remove the cables linked to the throttle body lever arm. Then, get rid of the four bolts keeping the throttle body on the manifold and set the old gasket aside. After cleaning where the throttle body and Intake Manifold meet, fit a new gasket in between and align the throttle body with the manifold. Get the tubes to hold the crankshaft snugly by using the four mounting bolts and tightening to 23 Nm (200 in. lbs.). Secure again the control cables, vacuum line and the electric connectors and next install the air cleaner.

  Q: How to Service and Repair a Throttle Body on a 5.7L V-8 on Dodge Ram 3500?

  A:

  First, examine and clean the condition of the throttle body-to-Intake Manifold O-ring 2 and then clean both the throttle body and the intake manifold mounting surfaces. After that, fit O-ring 2 on the sides of the throttle body and intake manifold before placing the throttle body onto its pins and putting all bolts in place by hand. It is necessary to tighten the mounting bolts exactly as required, avoiding over-tightening, since this may damage the throttle body, throttle plate, gaskets, bolts or the intake manifold and the throttle body has specific torque requirements for normal operation. Tighten the bolts that attach your wheels with a torque wrench, making sure they are even across the wheel set to 5.6 Nm (50 in. lbs.). Then, put in electrical connector 2, connect the air plenum to flange 3 and reconnect the negative Battery Cable. After that, erase all existing DTCs using the diagnostic scan tool followed by the ETC Relearn function.
