Basic procedure
a. Start the engine, warm it up for several
minutes, and then let it run at the specified
engine idling speed.
b. Turn the bypass air screw “1” with a white
paint mark out a little, and then turn it in
fully.
c. Using the throttle body that has the bypass
air screw with a white paint mark as the
standard, turn the bypass air screws with-
out white paint marks in or out to the adjust
the other throttle bodies.
TIP
• If more than one throttle body has a bypass
air screw with a white paint mark, use the
one with the lowest vacuum pressure as the
standard.
• After each step, rev the engine two or three
times, each time for less than a second, and
check the synchronization again.
