tighten attaching screws to 15 N´m (130 in. lbs.) (Fig.
31).
INTAKE MANIFOLDÐ3.3/3.8L ENGINE
REMOVAL
(1) Remove windshield wiper module. Refer to
Group 8K Windshield Wiper and Washer Systems for
procedure.
(2) Perform fuel system pressure release proce-
dure(before attempting any repairs).Refer to
Group 14 Fuel System for procedure.
(3) Drain cooling system. See Cooling System,
Group 7 for procedure.(4) Remove air inlet resonator to throttle body
hose assembly.
(5) Remove throttle cable. Refer to Group 14 Fuel
Systems for procedure. Remove wiring harness from
throttle cable bracket.

REMOVAL AND INSTALLATION (Continued)

(10) Disconnect MAP Sensor electrical connection
(Fig. 34).
(11) Remove EGR tube flange from intake ple-
num.
(12) Remove vacuum harness connectors from
intake plenum (Fig. 34).
(13) Remove cylinder head to intake plenum strut
(Fig. 35)
(14) Remove the engine mounted ground strap.
(15) Remove the fuel hose quick connect fitting
from the fuel line by using an open end wrench push-
ing in on the plastic ring located on the end of the
fittings. Gently pull the fitting from the fuel line
(Fig. 36).
WARNING: WRAP A SHOP TOWEL AROUND
HOSES TO CATCH ANY GASOLINE SPILLAGE DUR-
ING REMOVAL.
(16) Remove direct ignition system (DIS) coils and
generator bracket to intake manifold bolt (Fig. 37).(17) Remove bolts from generator to intake mani-
fold bracket. Loosen top generator mounting bolt,
and move bracket up so intake manifold can clear
