Secondary Ignition Components

WARNING: This page is about a different car, the 2004 GMC Sierra and 2004 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The distributor is only used as a means to operate the CMP sensor and to distribute spark in the correct sequence. Since the distributor has no influence on base timing the distributor is not adjustable on V6 engines. The distributor position can be adjusted on V8 engines because the chance of crossfire between terminals is greater due to the proximity of the terminals. The spark is distributed through conventional carbon core wires to the spark plugs. The plugs are tipped with platinum for long wear and higher efficiency.
