Cleaning
WARNING
!
Some carburetor cleaning chemicals,
especially dip-type soaking solutions, are
very corrosive and must be handled carefully.
Always follow the chemical manufacturer's
instructions on proper use, handling and
storage.
• Clean passageways with a spray-type carburetor
cleaner and blow dry with compressed air.
CAUTION
!
Do not use wire to clean passageways. Wire
can damage passageways. If the components
cannot be cleaned with a spray cleaner it may
be necessary to use a dip-type cleaning
solution and allow them to soak. Always
follow the chemical manufacturer's
instructions for proper use and cleaning of
the throttle body components. Do not apply
carburetor cleaning chemicals to the rubber
and plastic materials.
Inspection
Check following items for any defects or clogging.
Replace the throttle body if necessary.

ring is not available for the spare parts. If it is
found to be damaged, replace the ISC valve
assembly with new one.
