•
take the engine back to idle and check
the depression values so that they are
aligned between the two cylinders.
Otherwise, open only the screw with
higher depression, using the by-pass
screws, to compensate.
If there is a larger difference:
•
work on the set screw of the throttle
body connecting rod to reduce the
pressure difference in the two pipes.
•
Repeat the procedure "Throttle posi-
tion autodetection" as explained
above.
•
Bring the engine back to idle and check
the depression values so that they are
aligned between the two cylinders.
•
Otherwise, open only the screw with
higher depression, using the by-pass
screws, to compensate.
