Condition

Possible Cause

Reference Item

Surges
(Engine power variation
under steady throttle or
cruise.
Feels like the vehicle
speeds up and down
with no change in the
accelerator pedal.)

Ignition system out of order.

Defective spark plug (excess carbon
deposits, improper gap, and burned
electrodes, etc.)

Fuel system out of order.

Variable fuel pressure
– Clogged fuel filter
– Kinky or damaged fuel hose and line
– Faulty fuel pressure regulator

Engine and emission control system out
of order.

Faulty EGR system

Faulty MAF sensor

Faulty injector

Faulty ECM (PCM)

Excessive detonation
(The engine makes
sharp metallic knocks
that change with throttle
opening.
Sounds like pop corn
popping.)

Engine overheating

Ignition system out of order.

Faulty spark plug

Improper ignition timing

Fuel system out of order.

Clogged fuel filter and fuel lines

Engine and emission control system
out of order.

Faulty EGR system

Faulty ECT sensor or MAF sensor

Faulty injector

Faulty ECM (PCM)

Others

Excessive combustion chamber
deposits
