5. Setup and Installation
Installation of an ignition distributor requires specialized knowledge and tools. This part requires programming and/or special setup procedures. Refer to GM Service Information for detailed procedures and specific tools needed to ensure proper operation in your vehicle. Incorrect installation can lead to engine malfunction or damage.
General Installation Guidelines (Consult a Professional):
- Preparation: Ensure the vehicle's engine is cool. Disconnect the negative terminal of the battery.
- Access: Locate the existing distributor. Depending on the vehicle, this may require removing other components for access.
- Marking: Before removal, carefully mark the position of the distributor housing relative to the engine block, and the rotor position relative to the distributor housing. This is critical for correct timing.
- Disconnection: Disconnect all electrical connectors and vacuum lines from the old distributor. Remove the distributor cap and spark plug wires.
- Removal: Unbolt the old distributor from the engine block and carefully remove it, noting the orientation of the shaft gear.
- Installation of New Distributor: Align the new ACDelco Gold 88864773 distributor with the marks made during removal. Ensure the shaft gear engages correctly with the camshaft gear.
- Securing: Bolt the new distributor into place. Do not overtighten.
- Reconnection: Reconnect all electrical connectors, vacuum lines, and the distributor cap with spark plug wires in the correct firing order.
- Programming/Setup: As specified, this part may require programming or special setup procedures using diagnostic tools. This step is essential for proper function and must be performed by a qualified technician.
- Final Checks: Reconnect the battery. Start the engine and check for proper operation, ensuring no warning lights are illuminated and the engine runs smoothly.
Warning: Failure to follow proper installation and programming procedures can result in severe engine damage or improper vehicle operation.

6. Operating Instructions
The ACDelco Gold 88864773 Ignition Distributor operates as an integral part of your vehicle's ignition system. Once correctly installed and programmed, it works automatically to ensure the engine receives the necessary spark at the correct time for combustion.
- The internal switching device (sensor) detects the engine's rotational position.
- This signal is sent to the engine control unit (ECU) or ignition module.
- The ECU then commands the ignition coil to generate high voltage.
- The distributor rotor, rotating inside the distributor cap, directs this high voltage to the correct spark plug wire, which then delivers the spark to the corresponding cylinder.
Proper operation is indicated by smooth engine running, consistent power delivery, and the absence of misfires or rough idling. If you experience any issues after installation, refer to the troubleshooting section or consult a professional.

7. Maintenance
The ACDelco Gold 88864773 Ignition Distributor is designed for long-term reliability with minimal maintenance. However, periodic inspection of related components is recommended as part of your vehicle's regular service schedule.
- Distributor Cap and Rotor: Inspect the distributor cap and rotor for cracks, carbon tracking, or excessive wear at recommended service intervals (refer to your vehicle's service manual). Replace if necessary.
- Spark Plug Wires: Check spark plug wires for signs of damage, fraying, or corrosion. Ensure they are securely connected.
- Electrical Connections: Periodically inspect all electrical connections to the distributor for corrosion or looseness. Ensure they are clean and secure.
- General Cleanliness: Keep the area around the distributor clean and free of oil, dirt, and debris.
Always use genuine ACDelco replacement parts for optimal performance and compatibility.
