Spark Plug: Testing and Inspection
Electrode Gap Bridging

Electrode Gap Bridging

Symptoms: Gap between the electrodes bridged by deposits. 

Possible Causes:
-

Loose deposits in the combustion chamber can accumulate on the spark plug electrodes during continuous stop and-go driving. Then when the
engine is suddenly subjected to a high torque load, the deposits partially liquefy and bridge the gap between the electrodes, short circuiting the
electrodes. 

NOTE:  Spark plugs with electrode gap bridging can be cleaned using standard procedures.
