8. Remove the two rear bolts on back side of intake manifold to
heat-shield/support using a 6mm hex driver, and five bolts
holding upper intake manifold to lower intake runner using a
5mm hex driver. Carefully separate, and remove gasket. Clean
off any remaining gasket material. Immediately cover intake
runner ports with masking tape. Now is a good time to install the
new hi-performance Denso Iridium spark plugs. NOTE: Spark
plugs are pre-gapped. NOTE: Before removing old spark plugs,
use compressed air to blow out around plug recesses so that any
dirt will not fall into cylinder. Put anti-seize on threads! 6. THROTTLE BODY REMOVAL: Disconnect electrical
harness from throttle position sensor, vacuum hose from EVAP
canister purge valve, and coolant hoses. Remove four bolts using
#8 triple square driver, and lift off throttle body – move aside.
7. MANIFOLD REMOVAL: Disconnect brake servo vacuum
hose by cutting crimp-clamp, leak detection pump vacuum hose
from white plastic fitting, EVAP purge valve hose, and fuel
pressure regulator vacuum hose.
9. HEAT-SHIELD REMOVAL/ASSEMBLY: Disconnect hard
plastic air pump hose and secondary metal air pipe flare nut from
combi-valve. Loosen lower flange nut so that you can push pipe
out of fitting and rotate pipe towards driver side of vehicle to
allow removal. Remove three bolts using a 6mm hex driver and
one bolt using a 5mm hex driver – lift heat shield, and remove O
2
sensor. The heat shield can now be removed. Remove combi-
valve assembly using a 5mm hex driver. Remove combi-valve
gasket using a scraper or knife. Use new gasket supplied, and
transfer assembly to the new supplied heat-shield. Torque
combi-valve bolts to 7ft. lbs. Re-install heat shield, hoses, and
metal pipe in reverse of disassembly with factory bolts. Torque
heat-shield bolts to 18ft. lbs. Use Loctite on all bolts.
