Step Two – Remove the throttle cable and if you have a suicide throttle (interior hand throttle) cable remove it too…

  1. Use a small screw driver to pry the throttle cable end off the ball joint (Red Arrow)
  2. On my particular jeep I have an interior hand throttle control, its cable comes off by removing a hairpin clip (Yellow Arrow)

Step Five – Thoroghly clean the throttle body assembly (some basic tips)
I am not going into great detail as there are many docs and videos available showing this process

  1. Always use a throttle body cleaner, other cleaners may cause damage
  2. A well ventilated area is important (Outdoors is best)
  3. Rubber gloves and eye protection should be used during the cleaning process
  4. Lint free materials should be used, as well as a catch basin to work in
  5. Don’t scratch the walls or plate when cleaning, let the cleaner do the work
  6. Remove the idle speed stepper motor and clean it thoroughly as well as the ports it mates into
  7. You may lightly lubricate the pivot points of the plate when finished

Step Six – Installing

  1. Put the new Power Tower PLUS (engraved side toward the throttle body)
  2. Make sure you have a gasket above it (between the throttle body and Power Tower)
    and below it (between Power Tower and intake manifold)
  3. Install the four 6mm x 50mm bolts and 4 washers by hand first
  4. Tighten bolts evenly to 10Nm (89lb/in) (Yellow Arrows)
