Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Fuel Quality Improvement

Sub-steps:
1. Drain any low-octane fuel from the tank using a siphon pump.
2. Refill the tank with high-octane fuel as recommended by the manufacturer.
3. Add a fuel system cleaner to help remove deposits that may cause knocking.

3. Ignition Timing Adjustment

Sub-steps:
1. Locate the timing adjustment mechanism (consult repair manual).
2. Use a timing light to measure the current timing.
3. Adjust the timing according to the specifications (typically 10-16 degrees BTDC).
4. Re-check with the timing light to ensure proper adjustment.

4. Spark Plug Inspection and Replacement

Sub-steps:
1. Remove the spark plug wires and disconnect them carefully.
2. Use a socket set to remove the spark plugs.
3. Inspect plugs for wear; replace if the gap is beyond specifications or if they are fouled.
4. Install new spark plugs, ensuring proper torque (usually 13-15 ft-lbs) and gap settings.

5. Air Intake System Check

Sub-steps:
1. Inspect the air filter and replace it if dirty.
2. Check for any vacuum leaks in hoses connected to the intake.
3. Clean the throttle body using an appropriate throttle body cleaner.
