IGNITION TIMING
Ignition timing adjustment is not possible and should
not be attempted.
The timing advance range is programmed into the
ignition module, which responds to vacuum signal
(indicating engine load) and TDC sensor signal
(indicating engine flywheel position and rpm).
Timing is then adjusted automatically to correspond
with those conditions. (Refer back to IGNITION
MODULE.)
If timing is incorrect, check:
• vacuum lines
• TDC sensor
C BAD
E
• ignition module
DISTRIBUTOR (M)
The distributor cap and rotor arm feed high voltage
to each spark plug according to their firing order.
