CLEANING AND INSPECTION
IMPORTANT: DO NOT use cleaners containing
methyl ethyl ketone. It is not necessary for clean-
ing throttle bore and valve deposits.
IMPORTANT: DO NOT allow the TP and IAC valve
to come into contact with solvent or cleaner.
IMPORTANT: Use care when removing gasket
material from plenum and throttle body. Failure
to do so could result in damage to the plenum
and throttle body.
1. Carefully remove all gasket material from plenum
and throttle body.
2. Thoroughly clean all parts of throttle body. Make
certain that all passages are free of dirt and burrs.
3. Inspect mating surfaces for damage that could
affect gasket sealing.
4. Inspect throttle body for cracks in casting.
5. Inspect throttle plates, linkage, return springs,
etc., for damage, wear and foreign material.
6. Check plenum for loose parts and foreign
material.

NOTE: To prevent difficult removal of fasteners and
damage to fastener heads, do not use a higher
strength thread locking compound than recom-
mended.
1. Connect TP and IAC electrical connectors, then
install throttle body with new gasket using four
throttle body mounting studs.
