Fuel control link ball joint - Inspect
Check ball joint in the fuel control link for play. If the
amount of play is 0.1 mm [0.004 in.] or more, replace
the ball joint with the new one.
If the ball joints are integrated in the control link,
replace the control link when the ball joints have loos-
ened. When installing ball joints, be sure to tighten the
nuts firmly.
