Ignition Systems Features

The distributor ignition (DI) system features:

• A camshaft driven distributor (12127) which uses no centrifugal or vacuum advance.
• The distributor which has a diecast base which incorporates a Hall effect stator assembly.

Initial timing adjustments are not required unless:

• The distributor has been moved from its factory setting.
• The distributor has been removed from the engine.

Ignition timing procedures and diagnostics are found in Section 8A of the Powertrain Control/Emissions Diagnosis Manual .

NOTE: Do not change engine ignition timing by use of different octane rods without first having the proper authorization; federal emission requirements will be affected.
