Spark Plugs and Ignition Coils

Spark Plugs and Ignition Coils
The ignition system is responsible for producing and transferring the spark energy to the combustion chamber at the correct time. Spark plugs are installed in the cylinder head and deliver spark current to the combustion chamber. Symptoms of malfunctioning spark plugs include:
Hard starting
Lack of power
Misfiring or backfiring
High emissions
Reduced fuel economy
Ignition Coils:
Produce high voltage spark energy sufficient to properly ignite the air/fuel mixture inside the combustion chamber. The On-Board computer or ignition module typically controls ignition coils. Symptoms of malfunctioning ignition coils include:
No start
Hard starting
Misfire under a load
High emissions
Ignition Wires
Provides a conductive path for the spark current from the distributor cap or coil to the spark plugs. Contain the spark energy. Symptoms of malfunctioning ignition wires include:
Hard starting
Misfiring or backfiring
Misfire under a load
High emissions
Here are the Benefits of a Properly Maintained Ignition System
Quick starting
Increased performance
Increased fuel economy
Lower emissions
Cure specific driveability concern
Conserves spark energy for the combustion chamber
Regulates spark energy
