If you should notice misring, uneven running
or loss of power when the car is moving, have
the vehicle inspected by a specialised work-

will light up when any of these symptoms
occur. If this happens, any unburnt fuel can
enter the exhaust system and escape into the
atmosphere. The catalytic converter can also
be damaged by overheating.
