THROTTLE BODY AND INTAKE MANIFOLD
REMOVAL
1) Relieve fuel pressure according to procedure described in Sec-
tion 6.
2) Disconnect negative cable at battery.
3) Drain cooling system.
WARNING:
To help avoid danger of being burned, do not remove
drain plug (2) and radiator cap while engine and radiator
(1) are still hot. Scalding fluid and steam can be blown out
under pressure if plug and cap are taken off too soon.
4) Disconnect IAT sensor at coupler.
5) Remove air cleaner outlet hose (2) with resonator.
6) Disconnect accelerator cable (1) from throttle body.
