IGNITION SYSTEM PRECAUTIONS
When disconnecting wire from spark plug or distributor cap,
twist rubber boot slightly to loosen. Grasp boot (not wire) and pull
with steady, even force.
When separating control unit connectors, pull with firm,
straight force. Do not pry apart with screwdriver. When connecting,
press together firmly to overcome hydraulic pressure of silicone
grease.
Page 877 of 1378
Removal & Installation
Using care, disconnect the spark plug and coil wire boots and
wires. Twist the boot one half turn and pull on the boot to disconnect
the wire.
When replacing the spark plug and coil wires, carefully route
the wires correctly and secure them in their proper channels
retainers.
Failure to route the wires properly can cause the radio to
reproduce ignition noise, cross ignition of the plugs, or can short
circuit the wires to ground.
