How to the Change Spark Plugs on a 2002 Ford Focus Mk1 1.6 Zetec SE 101HP FYDA Euro 4.
In this video you can find all the documentation you need to inspect and change spark plugs on the 1.6 (and other) engines, in this case it's in my 2002 Ford Focus. The procedure is similar on all other gasoline engines. Diesel engines don’t have spark plugs, they have glow plugs, that’s a whole other story.

Reading Spark Plugs:

NORMAL
Recommendation: Correct heat range of spark plug is being
used. Replace with the equivalent Autolite spark plug at the
proper interval.

CARBON FOULED
Recommendation: Spark plug heat range is too cold and/
or caused by extensive low-speed, short distance driving.
Replace with the correct heat range of Autolite spark plug.
Also caused by weak ignition system and/or rich fuel mixture.
Fuel injection engines would produce carbon fouling from
clogged fuel injectors, vacuum leaks, and/or problem with
carbon canister/purge valve operation. Carburetor equipped
engines cause carbon fouling from improperly adjusted or
malfunctioning choke.

OIL DEPOSITS
Recommendation: Caused by presence of oil in the combus-
tion chamber. Check for worn rings, worn valve guides, and/
or worn valve seals.

ASH DEPOSITS
Recommendation: Caused by the use of leaded fuel, fuel
additives, and/or oil additives. Check for worn piston rings
and/or valve guides. Misfiring may occur due to the deposits
on the electrodes.

BURNED
Blisters on the insulator tip, melted electrodes, or white deposits are signs of a burned spark plug that is running too hot. Causes can include the engine overheating, incorrect spark plug heat range, a loose spark plug, incorrect ignition timing or too lean of an air/fuel mixture. The spark plug should be replaced.

FUEL FOULED
Recommendation: Indicates the cylinder from which the spark
plug came is not using all the fuel supplied to it. Check for
faulty or sticking choke, overly rich fuel mixture, ignition prob-
lems, leaking fuel injectors, or spark plug heat range is too cold.

WORN ELECTRODE
Worn and eroded electrodes are symptoms of a spark plug that is past its prime. The plug has been in the engine too long and needs to be replaced.

BROKEN ELECRTODE
If the electrodes are broken off or flattened, it is likely that the wrong spark plugs are installed. A spark plug that is too long can cause extensive damage to your engine while a short spark plug can cause poor gas mileage and spark plug fouling. Check your owner’s manual to ensure that you have the correct spark plug for your vehicle.

BROKEN INSULATOR
Spark plug wasn't handled correctly.
