THROTTLE CABLE—4.7L V-8 ENGINE

REMOVAL

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. 38).
Plastic cable retainer (clip) snaps into pedal arm.

(2) Remove cable core wire at pedal arm.

to dashpanel (Fig. 38).

(4) Remove air box at throttle body.
(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. 42). 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. 42).

(9) Press tab (Fig. 43) 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.
43) towards passenger side of vehicle to remove cable
from bracket.

(10) Remove throttle cable from vehicle.

INSTALLATION

(1) Slide

mount

into

bracket. Continue sliding until tab (Fig. 43) is
aligned to hole in mounting bracket.

(2) Route accelerator cable over top of cable cam.
(3) Connect cable end to throttle body bellcrank

pin (snaps on rearward).

(4) Slide rubber grommet away from plastic cable

housing.

(5) Install rubber grommet into dash panel until

seated.

(6) Push cable housing into rubber grommet and

through opening in dash panel.

(7) From inside vehicle, install clip holding cable

to dashpanel (Fig. 38).

(8) From inside vehicle, slide throttle cable core

wire into opening in top of pedal arm.

(9) Push cable retainer (clip) into pedal arm open-

ing until it snaps in place.

(10) Snap cable into dashpanel routing clip.

(11) Install air box to throttle body.
(12) Before starting engine, operate accelerator

pedal to check for any binding.

gasoline is not recommended. The use of premium
gasoline will provide no benefit over high quality reg-
ular gasoline, and in some circumstances may result
in poorer performance.

Light spark knock at low engine speeds is not

harmful to your engine. However, continued heavy
spark knock at high speeds can cause damage and
immediate service is required. Engine damage result-
ing from operation with a heavy spark knock may
not be covered by the new vehicle warranty.

Poor quality gasoline can cause problems such as

hard starting, stalling and hesitations. If you experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle.

Over 40 auto manufacturers world-wide have

issued and endorsed consistent gasoline specifications
(the Worldwide Fuel Charter, WWFC) to define fuel
properties necessary to deliver enhanced emissions,
performance and durability for your vehicle. We rec-
ommend the use of gasolines that meet the WWFC
specifications if they are available.

REFORMULATED GASOLINE

Many areas of the country require the use of

cleaner burning gasoline referred to as “reformulat-
ed” gasoline. Reformulated gasoline contain oxygen-

ates, and are specifically blended to reduce vehicle
emissions and improve air quality.

We strongly supports the use of reformulated gas-

oline. Properly blended reformulated gasoline will
provide excellent performance and durability for the
engine and fuel system components.

GASOLINE/OXYGENATE BLENDS

Some fuel suppliers blend unleaded gasoline with

oxygenates such as 10% ethanol, MTBE, and ETBE.
Oxygenates are required in some areas of the country
during the winter months to reduce carbon monoxide
emissions. Fuels blended with these oxygenates may
be used in your vehicle.

CAUTION: DO NOT use gasoline containing METH-
ANOL. Gasoline containing methanol may damage
critical fuel system components.

MMT IN GASOLINE

MMT is a manganese-containing metallic additive

that is blended into some gasoline to increase octane.
Gasoline blended with MMT provide no performance
advantage beyond gasoline of the same octane num-
ber without MMT. Gasoline blended with MMT
reduce spark plug life and reduce emission system
performance in some vehicles. We recommend that
gasolines free of MMT be used in your vehicle. The
MMT content of gasoline may not be indicated on the
gasoline pump; therefore, you should ask your gaso-
line retailer whether or not his/her gasoline contains
MMT.

It is even more important to look for gasoline with-

out MMT in Canada because MMT can be used at
levels higher than allowed in the United States.
MMT is prohibited in Federal and California refor-
mulated gasoline.

SULFUR IN GASOLINE

If you live in the northeast United States, your vehi-

cle may have been designed to meet California low
emission standards with Cleaner-Burning California
reformulated gasoline with low sulfur. If such fuels are
not available in states adopting California emission
standards, your vehicles will operate satisfactorily on
fuels meeting federal specifications, but emission con-
trol system performance may be adversely affected.
Gasoline sold outside of California is permitted to have
higher sulfur levels which may affect the performance
of the vehicle’s catalytic converter. This may cause the
Malfunction Indicator Lamp (MIL), Check Engine or
Service Engine Soon light to illuminate. We recom-
mend that you try a different brand of unleaded gaso-
line having lower sulfur to determine if the problem is
fuel related prior to returning your vehicle to an
authorized dealer for service.

CAUTION: If the Malfunction Indicator Lamp (MIL),

MATERIALS ADDED TO FUEL

All gasoline sold in the United States and Canada

are required to contain effective detergent additives.
Use of additional detergents or other additives is not
needed under normal conditions.

FUEL SYSTEM CAUTIONS

CAUTION: Follow these guidelines to maintain your
vehicle’s performance:

• The use of leaded gas is prohibited by Federal

law. Using leaded gasoline can impair engine perfor-
mance, damage the emission control system, and
could result in loss of warranty coverage.

• An out-of-tune engine, or certain fuel or ignition

malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.

• When pulling a heavy load or driving a fully

loaded vehicle when the humidity is low and the tem-
perature is high, use a premium unleaded fuel to

help prevent spark knock. If spark knock persists,
lighten the load, or engine piston damage may result.

• The use of fuel additives which are now being

sold as octane enhancers is not recommended. Most
of these products contain high concentrations of
methanol. Fuel system damage or vehicle perfor-
mance problems resulting from the use of such fuels
or additives is not the responsibility of Daimler-
Chrysler Corporation and may not be covered under
the new vehicle warranty.

NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
