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".
