Spark plugs


Check this SPARK PLUG REPLACEMENT - REMOVAL PROCEDURE

1_23_2012_5_10_32_pm.jpg

1. Remove the ignition coils (lines at end this document), then return here once you have gotten the Coil
Packs off and precede with step 2 from here.
2. Clean the spark plug recesses with low pressure air. CAUTION: Wear safety glasses
when using compressed air, as flying dirt particles may cause eye injury. NOTE:
Clean the spark plug recess area before removing the spark plug. Failure to do so could
result in engine damage because of dirt or foreign material entering the cylinder head, or
by the contamination of the cylinder head threads. The contaminated threads may prevent
the proper seating of the new plug. Use a thread chaser to clean the threads of any
contamination.
3. Remove the spark plugs from the cylinder head. NOTE: Allow the engine to cool before
removing the spark plugs. Attempting to remove the spark plugs from a hot engine may
cause the plug threads to seize, causing damage to cylinder head threads.
4. Inspect the spark plugs.

INSTALLATION PROCEDURE

1_23_2012_5_11_30_pm.jpg

1. Measure the spark plug gap on the spark plugs to be installed. Compare the measurement
to the gap specifications. NOTE:
• Use only the spark plugs specified for use in the vehicle. Do not install spark
plugs that are either hotter or colder than those specified for the vehicle. Installing
spark plugs of another type can severely damage the engine.
• Check the gap of all new and reconditioned spark plugs before installation. The
pre-set gaps may have changed during handling. Use a round feeler gage to ensure
an accurate check. Installing the spark plugs with the wrong gap can cause poor
engine performance and may even damage the engine.
2. Install the spark plugs to the cylinder head. NOTE:
• Be sure that the spark plug threads smoothly into the cylinder head and the spark
plug is fully seated. Use a thread chaser, if necessary, to clean threads in the
cylinder head. Cross-threading or failing to fully seat the spark plug can cause
overheating of the plug, exhaust blow-by, or thread damage.
• Refer to Component Fastener Tightening Notice in Service Precautions.
Tighten the spark plugs to 18 N.m (13 lb ft).
3. Install the ignition coils.

Um i have a 90 something crown vic... im wanting to run it in the demo derby... well my uncle come and cut all the wires out.... bad i know..... i can get the motor to turn over know prob.. is there a way...


Not without a specific wiring diagram--the computer needs a number of connections to run the engine. If it could be fitted with a carburetor and mechanical ignition distributor, it would be more easy, but still a lot of work just to take it out and destroy it.

Well.... I do not see the ignition module listed, which is mounted inside the distributor mentioned yet. Have you replaced it and just not listed it? The crank sensor could be too.....I just can't imagine having to cut a wiring harness. Never had to before... keep trying other things.
