PROBLEM SYMPTOMS TABLE (FOR YOUR INFORMATION)
ITEMS
SYMPTOM
At starting
Won't start
The starter cranks the engine, but there is no combustion within the
cylinders, and the engine won't start.
Starts up and
dies
The engine starts, but then engine soon stalls.
Hard starting
Engine starts after cranking a while.
Idling stability Hunting
Engine speed doesn't remain constant; changes at idle.
Rough idle
Usually, a judgement can be based upon the movement of the
tachometer pointer, and the vibration transmitted to the steering wheel,
shift lever, body, etc.
Incorrect idle
speed
The engine doesn't idle at the correct speed.
Engine stall (die
out)
The engine stalls when the foot is taken from the accelerator pedal,
regardless of whether the vehicle is moving or not.
Engine stall (pass
out)
The engine stalls when the accelerator pedal is depressed.

At driving
Hesitation Sag
"Hesitation" is the delay in
response of the vehicle speed
(engine speed). This occurs
when the accelerator is
depressed in order to accelerate
from the speed at which the
vehicle is now traveling, or a
temporary drop in vehicle speed
(engine speed) during such
acceleration.
Serious hesitation is called
"sag".
Poor acceleration Poor acceleration is inability to obtain an acceleration corresponding to
the degree of throttle opening, even though acceleration is smooth. Also
the inability to reach maximum speed.
Stumble
Engine speed increase is
delayed when the accelerator
pedal is initially depressed for
acceleration.
Shock
The feeling of a comparatively large impact or vibration when the engine
is accelerated or decelerated.
Surge
This is slight acceleration and deceleration feel usually felt during
steady, light throttle cruise. Most notable under light loads.
Knocking
A sharp sound during driving, which sounds like a hammer striking the
cylinder walls. It makes poor driveability.
At stopped
Run on
("Dieseling")
The condition in which the engine continues to run after the ignition
switch is turned to the "LOCK" (OFF) position. Also called "dieseling".
