Engine starts after cranking a while.
Engine speed doesn’t remain constant; changes at id le.
Usually, a judgement can be based upon the movement of the tachometer
pointer, and the vibration transmitted to the steer ing wheel,
lever, body,
etc. This is called rough idle.
The engine doesn’t idle at the usual correct speed.
The engine stalls when the foot is taken from the
pedal, regardless
of whether the vehicle is moving or not.
The engine stalls when the accelerator pedal is dep ressed or being
used.
“Hesitation” is the delay in response of the vehicle speed (engine speed) that
occurs when the accelerator is depressed in order t o, accelerate from the
speed at which the vehicle is now traveling, or a drop in
speed (engine speed) during such acceleration.
Serious hesitation is called to

degree of throttle opening, even though acceleratio n is smooth, or the

If the play is equivalent to or exceeds the limit,

(3) If the play does not exceed the limit specifica tion,
install the brake disc at a position

brake disc once again.
If the run-out cannot be corrected by changing the phase
of the brake disc, replace the brake disc or turn rotor
with an on the car type brake lathe

equivalent). Be sure to follow the exact brake lath e
manufacturer instructions. Rotors turned on the veh icle
will often have a lower run-out than a new brake di sc.
