regulator from the air cleaner housing.
Recover the gasket.
Refitting
4 Refit the regulator by following the removal
procedure in reverse. Use a new gasket.
Removal
1 Remove the throttle body air box/air cleaner
as described in Section 2.
2 At the throttle body, disconnect the
accelerator cable inner from the throttle valve
spindle plate (see illustration).
3 Remove the adjustment clip and extract the
cable outer from the mounting bracket (refer
to illustration 4.2).

remove the facia trim panels from underneath
the steering column.
5 Working under the facia, depress the
accelerator pedal slightly, then unclip the
accelerator cable end from the pedal
extension lever (see illustration).
6 At the point where the cable passes
through into the engine bay, prise the
grommet out from the bulkhead.
7 Release the cable from its clips (where
applicable) and guide it out through the
aperture in the bulkhead, into the engine bay.
Refitting
8 Refit the accelerator cable by following the
removal procedure in reverse.
Adjustment
9 At the throttle body, fix the position of the
cable outer in its mounting bracket by
inserting the metal clip in one the locating
slots, such that when the accelerator is
depressed fully, the throttle valve is held wide
open to its end stop.

Removal
Observe the
precautions in Section 1 before
working on any component in
the fuel system.
1 Refer to Section 2 and remove the air
cleaner/throttle body air box.
2 Refer to Section 9 and depressurise the fuel
system, then disconnect the battery negative
cable and position it away from the terminal.
3 Disconnect the fuel supply and return
hoses from the ports on the side of the throttle
body. Note the arrows that denote the
direction of fuel flow, and mark the hoses
accordingly (see illustration).
4 Unplug the wiring harness from the throttle
body at the connectors, labelling them to aid
correct refitting later. Similarly, disconnect all
vacuum hoses from the throttle body and
label them carefully; it is essential that the
hoses are reconnected to the correct vacuum
ports on reassembly.
5 Refer to Section 4 and disconnect the
accelerator cable from the throttle body.
6 Remove the through-bolts and lift the upper
and lower sections of the throttle body away
from the inlet manifold.
7 The lower section of the throttle body may be
separated from the upper section by releasing
the clips. If required, the inter-mediate flange
may be detached from the inlet manifold by
removing the nuts from the four through-bolts.
Refitting
8 Refitting is a reversal of removal; renew all
gaskets where appropriate. Finally, check and
if necessary adjust the accelerator cable.
