lntake Air System
Throttle Body
Description
The throttle body is ot the single-barrel side-draft 1ype.
The lower portion of the throttle valve is heated by en-gine coolant from the cylinder head. The idle adjusting
screw which increases/dec.eases bvDass air and the
Evaporative Emission (EVAP) Control Canister port are
located on the top of the throttle body.

1. Start the engine. Hold the engine at 3,OOO rpm with
no load (A/T in S or E position, M/T in neutral) until
the radiator fan comes on, then let it idle.
2. Disconnect the vacuum hose (to the EVAP control
canister) from the top of the throttle body; connect
a vacuum, gauge to the throttle body.

3. Allow the engine to idle and check that the gauge
indicates no vacuum.
a li there is vacuum, check the throttle cable (see
page 1 1-'l 18, 119).
Check that vacuum is indicated on the gauge when
the throttle is opened slightly from idle.
a lf the gauge indicates no vacuum, check the throt-
tle body port. lf the throttle body port is clogged.
clean it with carburetor cleaner.
Stop the engine and check that the throttle cable
operates smoothly without binding or sticking.
a lf there are any abnormalities in the above steps,
check for:
- Excessive wear or Dlav in the throttle valve shaft.
Sticky or binding throttle lever at full close po-
srtron.
Clearance between throttle stop screw and throt-
tle lever at tull close Dosition.

Emission Control System
SystemDescription
The emission control system includes a Three Way Cata-
lytic Convener (TWC), Positive Crankcase Ventilation(PCV) system and Evaporstive Emission {EVAP) Contfol
syst€m. The emission control system is designed to meet
federsl and stats emission standards.

Pressure Control
Low assist at higher speeds:
When steering resistance is low. such as when driving at high speeds. or when driving straight ahead, the input shaft is
near or in the neutral position, so there is little or no flow to any of the power cylinder orifices, Most of the feed pressure
trom the pump is bypassed to the reservoir. Because of this, the pressure stays the same in both sides of the power cylin-
der, resulting in low or no assist.
vaz =- S\->/-\7/RETURN PASSAGE(To RESERVOIRI
VALVE UNITINPUT SHAFT
High assist at lower speeds:
When steering resistance is high, such as when driving at low speed, or when turning the wheel with the car stopped, the
difference in angle created between the input shaft and the valve opens the fluid passage on one side, and closes the fluid
passage on the other side, at each pair of orifices. The fluid pressure increases in the side of the power cylinder fed by the
larger fluid passage. This increased pressure pushes on the rack piston, allowing the steering wheel to be turned with light
effon. On the other side of the power cylinder, the return passage opens allowing the steering fluid to return through the
input shaft to the reservoir. The fluid passages to the power cylinder automatically change in size, increasing as the steer-
ing resistance increases. In other words, the passages become larger and power assist increases when the steering effort
would normally be high, (for example. when parking or making low speed turns). and the passages become smaller and
power assist decreases when the steering effort would normally be low, (for example, when driving at high speeds or
straight ah€ad).
