11 - 10 EXHAUST SYSTEM AND INTAKE MANIFOLD
REMOVAL AND INSTALLATION (Continued)
(4) Inspect quick connect fittings for damage,
replace if necessary Refer to Group 14, Fuel System
for procedure. Lube tube with clean 30w engine oil,
Connect fuel supply hose to fuel rail assembly. Check
connection by pulling on connector to insure it locked
into position.
(5) Install throttle body. Tighten fastener to 22
N·m (200 in. lbs.).
(6) Connect Manifold Absolute Pressure/Intake Air
Temperature Sensor (TMAP) wiring connector.
(7) Connect knock sensor connector and starter
wires. Connect wiring harness to intake manifold
tab.
(8) Connect Idle Air Control (IAC) motor and
Throttle Position Sensor (TPS) wiring connectors.
(9) Connect vacuum hoses to throttle body.
(10) Install accelerator, kickdown and speed con-
trol cables to their bracket and connect them to the
throttle lever. Refer to Group 14, Fuel System Throt-
tle Body Installation for procedure.
(11) Loose assemble the EGR tube onto valve and
intake manifold finger tight. Tighten tube fasteners
at the EGR valve first to 11 N·m (95 in. lbs.) then,
tighten the intake manifold side fasteners to 11 N·m
(95 in. lbs.).
(12) Install clean air duct.
(13) Install fresh air duct to air filter housing.
Tighten clamp to 3 N·m (25 in. lbs.).
(14) Connect negative battery cable.
(15) With the DRB scan tool use ASD Fuel System
Test to pressurize system to check for leaks.
CAUTION: When using the ASD Fuel System Test,
the Auto Shutdown (ASD) relay will remain ener-
gized for 7 minutes or until the ignition switch is
turned to the OFF position, or Stop All Test is

tighten to 23 N·m (200 in. lbs.) starting at center and
progressing outward in both directions. Repeat this
procedure until all fasteners are at specified torque.
(2) Install exhaust manifold heat shield.
(3) Connect upstream heated oxygen sensor con-
nector.
(4) Install air cleaner bracket and assembly.
