Spark Kill Test (not available on catalyst equipped engines)
This test allows individual spark outputs to be disabled. This test should be per-
formed with the engine under a moderate load within an RPM range of 1000 and
2000 rpm. Running the engine under a moderate load will allow you to audibly
hear a drop in engine speed when the spark output is disabled. Upon selecting
this test you will be prompted to select the spark output, 1 thru 8, to disable.
Spark outputs follow cylinder number order. Use the ▲ and ▼ keys to select the
desired spark output and then press the TEST key to start the test. The test will
run for approximately 10 seconds.

numbers follow cylinder number order. Use the ▲ and ▼ keys to select the de-
sired fuel injector and then press the TEST key to start the test. The test runs for
