Installation
1) To install, reverse removal procedure. Injectors may be
removed after fuel rail is removed from intake manifold. Use new
insulators and "O" rings when installing injectors.
2) Use spindle oil or gasoline on "O" ring. Install injectors
into fuel rail with a twisting motion. Adjust throttle and kickdown
cable (if applicable). Do not drop injectors while removing or
installing fuel rail.
OXYGEN (O2) SENSOR
Removal & Installation
1) O2 Sensor is mounted in exhaust pipe below exhaust header.
It is equipped with a permanent pigtail which must be protected from
damage when sensor is removed. Ensure sensor is free of contaminants,
avoid using cleaning solvents of any type. Sensor may be difficult to
remove when engine temperature is less than 120
F (48 C).
2) Always use anti-seize compound on threads before
installation. On non-turbo models, remove sensor using Remover
(MD998703). On turbo models, use Remover (MD998748) on Eclipse and
Galant, or Remover (MD998770) on Stealth and 3000GT. Tighten oxygen
sensor to specification. See TORQUE SPECIFICATIONS table.
THROTTLE BODY
Removal
Disconnect air intake hose. Remove accelerator and automatic
speed control cables (if equipped). Disconnect fuel vapor hose,
electrical harness connector, vacuum hose and coolant hoses. Remove
throttle body retaining bolts.
Disassembly
Remove throttle position sensor. Remove idle speed control
motor. Remove throttle bracket and connector bracket (if equipped).
Remove idle position switch and adjusting nut.
NOTE: DO NOT remove throttle valve. DO NOT use cleaning solvents
on throttle position sensor, idle speed control motor or
idle position switch.
Cleaning
Clean all parts except those noted in solvent. Check vacuum
port and passage for clogging. Clean vacuum, vapor and fuel passages
with compressed air.
Reassembly
To reassemble, reverse disassembly procedure.
Installation
To install, reverse removal procedure.
THROTTLE POSITION SENSOR/SWITCH
Removal & Installation
Throttle position sensor/switch is located on throttle body.
Disconnect TPS electrical connector. Remove bolts holding TPS and
remove TPS. To install, reverse removal procedure. Tighten throttle
position sensor/switch to specification. See TORQUE SPECIFICATIONS
table. For adjustment procedure, see ON-VEHICLE ADJUSTMENTS article.
TURBOCHARGERS

intake hoses and EGR pipe. Disconnect oxygen sensor electrical
connector.
2) Remove oil pipe and EGR valve. Disconnect exhaust fitting
and remove rear heat protector. Remove oil return pipe. Remove
turbocharger assembly. See Fig. 11.

Inspection
Check turbine and compressor wheels for cracking and other
damage. Make sure turbine and compressor wheels turn smoothly. Check
for oil leakage from turbocharger assembly. Check for proper wastegate
valve operation. See SYSTEM & COMPONENT TESTING article.
Installation
1) To install, reverse removal procedure. Before oil pipe
flare nut (above turbocharger) is installed, pour clean engine oil
into turbocharger. Ensure oil and air hoses are properly installed and
securely clamped.
2) Use new gaskets. Adjust accelerator cable (if necessary).\
Refill engine oil and coolant. Check for oil and coolant leaks.
Tighten all bolts to specification. See TORQUE SPECIFICATIONS table.

touching a metal ground point on the vehicle prior to
servicing any ESD sensitive component.
ENGINE OIL
CAUTION: Never use non-detergent or straight mineral oil.
FUEL SYSTEM SERVICE
WARNING: Relieve fuel system pressure prior to servicing any fuel
system component (fuel injection models).
HALOGEN BULBS
Halogen bulbs contain pressurized gas which may explode if
overheated. DO NOT touch glass portion of bulb with bare hands. Eye
protection should be worn when handling or working around halogen
bulbs.
POWER STEERING FLUID
When adding power steering fluid, avoid spilling. Damage to
alternator, located beneath power steering reservoir, could result.
RADIATOR CAP
CAUTION: Always disconnect the fan motor when working near the
radiator fan. The fan is temperature controlled and could
start at any time even when the ignition key is in the OFF
position. DO NOT loosen or remove radiator cap when cooling
system is hot.
RADIATOR FAN
WARNING: Keep hands away from radiator fan. Fan is controlled by a
thermostatic switch which may come on or run for up to 15
minutes even after engine is turned off.
