5 Disconnect the fuel lines from the carburetor and cap the fittings to
prevent leakage (see Chapter 4).
6 Disconnect the throttle cable from the carburetor (see Chapter 4).
7 Detach the cable which runs from the carburetor to the transmission
(automatic transmission models only) and the cruise control cable, on ve-
hicles so equipped.
8 Unbolt the intake manifold and remove it from the engine (see
illus-
tration).
If it sticks, tap the manifold with a soft-face hammer.
Caution: Do
not pry between gasket sealing surfaces or tap on the carburetor.
Fuel-injected models
Refer to illustration 11.15
9 Remove the air intake hose (see Chapter 4).
IO Clearly label and disconnect ail hoses, wires, brackets and emission
lines which run to the fuel injection system. and intake manifold.
11 Remove the distributor (see Chapter 5) and the accelerator cable(s)
(see Chapter 4).
12 Remove the bolts that retain the air intake plenum to the intake man-
ifold (see Chapter 4). Remove the plenum.
13 Remove the bolts that hold the fuel rail to the intake manifold then re-
move the fuel rail (see Chapter 4).
14 Raise the vehicle and support It securely on jackstands.
15 Remove the bolts that retain the lower intake manifold bracket to the

(see illustration).
16 Unbolt the intake manifold and remove it from the engine. If it sticks,

12.3 Working under the vehicle, apply penetrating oil to the
threads and remove the nuts (arrows) - note that one is hidden
from view
moving all traces of gasket material.
18 Install the manifold, using a new gasket. Tighten the nuts in several
