Throttle control
First, check whether the throttle operating
line is deformed, kinked or damaged. Then
measure the free stroke of the throttle
handle. Turn the handle to one side of the
free stroke, draw a straight line between
the handle and the counterweight with a
marker pen, then turn the handle to the
other side of the free stroke, and measure
the distance of the straight line staggering,
which is the free stroke of the throttle
handle.
The free stroke is 2-6 mm.
If the free stroke is not enough or too large,
it shall be adjusted.
Adjustment method:
Idle speed
Note:
After other items of the engine have
been adjusted to the specified range,
check and adjust the idle speed.
The idle speed of the car is controlled by
ECU. The idle air flow of throttle body has
been adjusted at the factory. Therefore, do
not adjust the idle speed adjusting screw.
When the idle speed is unstable, there is
no idle speed or the idle speed is too high,
please find out the cause of the fault
according to the troubleshooting method of
EMS system and remove the fault.
Idle speed 1500r/ min ± 100r/ min。
