Step
12 Visually/Physically inspect the secondary ignition
wires. Check for the following conditions.
f
Verify that all ignition wire resistance are less than
the specified value.
f
Verify that ignition wires are correctly routed to
eliminated cross–firing.
f
Verify that ignition wires are not arcing to ground.
Spraying the secondary ignition wires with a light
mist of water may help to locate an intermittent
problem.
Was a problem found?
13 1. Check ignition coil secondary resistance.
2. Replace the coil if it is not within the specified range
of resistance.
Did the coil require replacement?
14 1. Remove the spark plugs and check for gas or oil
fouling, cracks, wear, improper gap, burned
electrodes, heavy deposits or improper heat range.
2. If spark plugs are fouled, the cause of fouling must
be determined before replacing the spark plugs.
Was a problem found?
15 1. Check the injector connectors.
2. If any of the connectors are connected at an
improper cylinder, correct as necessary.
Was a problem found?
16 Check the PCM grounds to verify that they are clean
and tight. Refer to the PCM wiring diagrams in
Electrical Diagnosis.
Was a problem found?
17 Visually/physically check the vacuum hoses for splits,
kinks and proper connections and routing as shown on
the "Vehicle Emission Control Information" label.
Was a problem found?
18 Check the exhaust system for a possible restriction:
f
damaged or collapsed pipes
f
internal muffler failure
f
Refer to Restricted Exhaust System Check to
measure back pressure and determine if the
catalytic converter is plugged.
19 1. Review all the diagnostic procedures within this
table.
2. If all procedures have been completed and no
malfunctions have been found, review/inspect the
following:
f
Visual/physical inspection.
f
Tech 2 data.
f
Freeze Frame data/Failure Records buffer.
f
All electrical connections within a suspected
circuit and/or system.
