Intake Air System
Throttle Body
Doscription
The throttle body is a single-barrel side-draft type. The
lower portion of the throttle valve is heated by engine
coolant from the cylinder head. The idle adjusting screw
which regulates the bypass air is located on the top of
the throttle bodv.
The illustration shows'97 - 98 models,'99 - 00 rnodelsare similar.
1 1-196
lnspection
Check that the throttle cable operates smoothly without
binding or sticking.
lf there are any abnormalities, check for:. Excessive wear or play in the throftle valve shaft.. Sticky or binding throttle lever at the fully closed posi-
tton.
. Clearance between throttle stop screw and throttle
lever at the fully closed position.
97 - 98 models:
THROTTLE LINKAGE
Replace the throttle body if there is excessive play in the
throttle valve shaft or if the shaft is binding or sticking.

Master Cylinder/Brake Booster
Removal/lnstallation
1, Disconnect the brake fluid level switch connectors.
2. Remove the reservoir cap from the master cylinder.
3. Remove the brake fluid from the master cvlinder
reservoir with a syringe.
4. Disconnect the brake lines from the master cylinder.
To prevent spills, cover the line joints with rags or
shop towels.
5. Remove the master cylinder mounting nuts and
wasners.
6. Remove the master cylinder from the brake booster.
CAUTION: Be careful not to bend or damage the
brake lines when removing the master cylinder.
Do not spill brake fluid on the vehicle; it may dam.
age the paint; it brake fluid does cont.ct the paint,
wash it oft immediately with water.
7. Disconnect the vacuum hose from the brake booster.
8. Remove the cotter pin and clevis pin from the clevis.
Do not disconnect the clevis by removing it from
the operating rod of the brake booster. lf the clevis
is loosened, adjust the pushrod length before
installing the brake booster (see page 19-15).

clear of the bulkhead.
11. Remove the brake booster from the enqine com-
panment.
12. Install the brake booster and master cylinder in the
reverse order of removal, and note these items:
. When connecting the brake lines, make sure that
there is no interference between the brake lines
and other parts.
. Be careful not to bend or damage the brake lines
when installing the master cylinder.
. lf replacing the master cylinder or brake booster,
check and adjust the pushrod clearance before
installing the master cylinder (see page 19-14).
Fill the master cylinder reservoir, and bleed the
brake system (see page 19-7).
After installation, check the brake pedal height and
brake pedal free play (see page 19-5), and adjust if
necessary.
