Page 690 of 1333
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
Page 691 of 1333
NOTE: Removal of turbocharger exhaust housing and water pipes at
turbocharger is not necessary when removing turbocharger
assembly. Stealth and 3000GT models have 2 (front and rear)
turbochargers.
Removal (Eclipse & Galant)
1) Disconnect negative battery cable. Drain engine coolant
and oil. On models with A/C, remove condenser fan motor assembly. On
all models, remove oxygen sensor. Remove oil dipstick guide and "O"
ring. See Figs. 8 and 9.

2) Disconnect air intake hose and vacuum hoses. Remove air
hose and air outlet housing. Remove heat protectors. Disconnect
exhaust pipe. Remove power steering oil pump and bracket. Remove
engine hanger bracket. Disconnect oil inlet pipe.
3) Disconnect coolant hose and tubes. Remove nuts and bolts
securing exhaust manifold. Remove exhaust manifold and gaskets.
Disconnect oil return pipe. Remove turbocharger assembly.
Removal (Stealth & 3000GT Front)
1) Disconnect negative battery cable. Drain engine oil and
coolant. Remove radiator. Disconnect exhaust pipe. Remove air intake
hose, air hoses and air pipe. Remove alternator and belt. Remove oil
dipstick guide.
2) Remove heat protector. Disconnect oxygen sensor electrical
connector. Remove oil return pipe. Remove turbocharger support bracket
and remove turbocharger from exhaust manifold. See Fig. 10.

Removal (Stealth & 3000GT Rear)
1) Disconnect battery cables and remove battery. Drain engine
oil and coolant. Remove accelerator cable. Remove air hose, air pipe
and heat protectors. Disconnect clutch booster vacuum hose. Remove air
Page 693 of 1333
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.
