Installation Instructions
131. Reinstall the motor housing cap by lining up the tabs
and applying light pressure.
132. Reuse the stock bolts to install the TPS on the new
throttle body by lining up the locating tab and pushing it
straight on. Be careful to avoid rotating the TPS during
installation.
133. Verify correct installation by pushing the butterfly
open and closed a few times, making sure that it doesn't
stick or bind in a particular position. Be sure that the
throttle blade returns to the closed position when released
before proceeding.
134. Align the throttle body gasket on the flange, then
install the throttle body onto the inlet elbow with the bolts
supplied in hardware bag #4. Open the throttle blade and
align the two parts so that there is a smooth transition
before tightening the bolts.
135. Use a cut off wheel or hacksaw and drill to cut the
base of the airbox off as shown, then reinstall the airbox.
