Worn spark plugs and plug wires can cause clogged catalytic converter or wear and tear to ignition coils and O2 sensors, main to more costly repairs.

As a part of the engine management system, the mass airflow sensor helps adjust to conclusive changes, like altitude. If your VW Golf is having trouble starting, idling rough or has a sudden change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
