REMOVAL - EXCEPT 4.7L
CAUTION: Be careful not to damage or kink cable
core wire (within cable sheathing) while servicing
accelerator pedal or cables.
(1) From inside vehicle, hold up accelerator pedal.
Remove plastic cable retainer and throttle cable core
wire from upper end of pedal arm (Fig. 22). Plastic
cable retainer snaps into pedal arm.
(2) Remove cable core wire at pedal arm.
(3) From inside vehicle, pinch both sides of cable
housing retainer at dash panel (Fig. 22). Remove
cable housing from dash panel and pull into engine
compartment.
(4) Remove air tube at top of throttle body.
(5) 3.9/5.2/5.9L Engines:
(a) Operate throttle body lever (by hand) to full
open throttle position. Slip cable end rearward
from pin on throttle lever (Fig. 55).
(b) Remove
cable
housing
at
throttle
body
mounting bracket by pressing forward on release
tab with a small screwdriver (Fig. 56). To prevent
cable housing breakage, press on tab only
enough to release cable from bracket. Lift
cable housing straight up from bracket while press-
ing on release tab. Remove cable housing.
(6) 2.5L Engine:
(a) Remove cable ball socket at throttle body
linkage (snaps off toward rear of vehicle).
(b) Pinch sides of cable housing clips at cable
mounting bracket (Fig. 57) to release housing from

CAUTION: Be careful not to damage or kink the
cable core wire (within the cable sheathing) while
servicing accelerator pedal or throttle cable.
(1) From inside vehicle, hold up accelerator pedal.
Remove plastic cable retainer (clip) and throttle cable
core wire from upper end of pedal arm (Fig. 22).
Plastic cable retainer (clip) snaps into pedal arm.
(2) Remove cable core wire at pedal arm.
(3) From inside vehicle, remove clip holding cable
to dashpanel (Fig. 22).

(5) Unsnap cable from dashpanel routing clip.
(6) Remove cable housing from dash panel and
pull into engine compartment.
(7) Using finger pressure only, disconnect accelera-
tor cable connector at throttle body bellcrank pin by
pushing connector off bellcrank pin towards front of
vehicle (Fig. 58). DO NOT try to pull connector
off perpendicular to the bellcrank pin. Connec-
tor will be broken.
(8) Lift accelerator cable from top of cable cam
(Fig. 58).
(9) Press tab (Fig. 59) to release plastic cable
mount from bracket. Press on tab only enough to
release cable from bracket. If tab is pressed too
much, it will be broken. Slide plastic mount (Fig.
59) towards passenger side of vehicle to remove cable

(c) Attach cable housing at valve cover retainer
(snaps on).
(3) Install remaining cable housing end into dash
panel opening (snaps into position).
(4) Install ball end of cable wire through hole in
pedal arm. Install plastic cable retainer. The plastic
retainer is snapped into pedal arm. When installing
retainer to accelerator pedal arm, note index tab on
pedal arm (Fig. 23). Align index slot (Fig. 57) on plas-
tic retainer to this index tab.
(5) Operate
and
test
throttle
before
starting
engine.
(6) Install air tube to throttle body.
