◆
Dirty or the damaged spark plug insulator or boot allows the spark
“tracking”
across the insulator.
◆
Rich mixture. Most likely due to the leaking fuel injector, or the faulty oxygen
sensor.
◆
Low cylinder compression pressure. It may be caused by the leaking valves, worn
piston ring, blown cylinder head gasket, etc.
4.4 Common causes of short burn time readings
◆
Spark plug is worn or the gap is too wide.
◆
Spark plug connector is damaged, loose or disconnected.
◆
The resistance of the ignition coil primary circuit is excessive.
◆
Lean mixture.
4.5 Common causes of low spark KVolt readings
◆
Short circuit, dirty or the gap of the spark plug is too small.
◆
Dirty or the damaged spark plug insulator or boot allows the spark
“
tracking
”
across the insulator.
◆
The core of the spark plug wire is broken. The break is located between the
distributor ( or DIS coil ) and the test point.
◆
Short circuit, disconnection or partial disconnection between the distributor ( or DIS
coil ) and the spark plug.

Rich mixture. Most likely due to the leaking fuel injector, or the faulty oxygen
sensor.
