THROTTLE BODY SERVICE
(1)Disconnect negative battery cable.
(2)Remove air cleaner hose clamp to throttle body and remove hose. (Fig. 1)
(3)Remove throttle cable and transaxle linkage.
(4)Disconnect automatic idle speed (AIS) motor and throttle position sensor (TPS) wiring connectors.
(5)Disconnect vacuum hoses from throttle body.
(6)Remove throttle body to intake manifold attaching nuts. Remove engine harness wiring bracket.
(7)Remove throttle body and gasket.
(8)Reverse the above procedures for installation. Tighten throttle body mounting nuts to 25 NIm (225 in. lbs.) torque.
THROTTLE BODY
When servicing body components, always assemble components with new O-rings and seals where applicable (Fig. 2). Never use lubricants on O-rings or seals, damage may result. If assembly of component

is difficult, use water to aid assembly. Use care when removing hoses to prevent damage to hose or hose nipple.
