1.0 DISASSEMBLY
1.1 Release the airflow meter harness 7-pin con-
nector by lifting the small wire clip that runs
around the rectangular base of the connector.
Remove the stock air flow meter, air filter box
and intake snorkel. Remove the air flow meter
from the air box. Store the air box, filter, and
snorkel away. Move the air flow meter to a safe
place on a worktable.
1.2 Remove the molded rubber elbow and hard
plastic tube that lead from the throttle body to the
airflow meter. If you have cruise control, you will
also have to remove the vacuum line from the
intake manifold nipple and from the points where
it attaches to the hard plastic intake tube.
Remove the cruise control vacuum line from the
cruise actuator as well and save it for use in a
later step.
1.3 Remove the chrome crankcase vent pipe that
is attached to the front of the cam cover and the
rubber hose that leads into the cam cover (Figure
1.4). These can be stored away. However, find
the small restrictor inside the rubber hose that
ran from the cam cover to the chrome tubing. It
can be felt as a lump in the straight section of the
hose near the chrome tube end. Persuade it out
by gently clamping the hose with a pair of pliers
just behind the “lump”. Save this restrictor for
step #7.8. Re-install the chrome bolts that held
the tubing in place. Store the chrome tube and
Mazda hoses away.
2.0 THROTTLE BODY
2.1 Remove the throttle body (Figure 1.4) by
releasing the two electrical connectors (one has
a spring wire, one has a plastic lever clip), the
two small coolant hoses on either side of the
lower Idle Control System (ICS) valve, and the
four bolts.
TIP: THE SPRING HOSE CLAMPS FROM
MAZDA ARE BEST REMOVED BY
APPROACHING FROM THE SIDE WITH NEE-
DLE NOSE PLIERS. GRASP ALL THREE
TANGS AT ONCE AND COMPRESS THEM
TOGETHER. THIS IS EASIER TO DO WITH
THE THROTTLE BODY ALREADY LOOSE
FROM THE INTAKE MANIFOLD.
