Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Ensure the vehicle is on a level surface and secured with jack stands if elevated.

2. Fuel System Inspection

Sub-steps:
1. Drain the fuel tank and refill it with a high-octane fuel to eliminate fuel quality issues.
2. Inspect the fuel filter for clogs and replace if necessary.
3. Check fuel injectors for proper operation and clean if needed.

3. Ignition Timing Adjustment

Sub-steps:
1. Connect the timing light to the battery and ignition coil according to the manufacturer's instructions.
2. Start the engine and allow it to warm up to normal operating temperature.
3. Point the timing light at the timing marks on the engine and adjust the distributor or ECU settings to achieve the correct timing specification as per service manual.

4. Spark Plug Inspection and Replacement

Sub-steps:
1. Remove the spark plugs using a spark plug socket and ratchet.
2. Inspect the spark plugs for wear, carbon buildup, or damage. Replace with OEM spark plugs if necessary.
3. Check the spark plug gap using a feeler gauge and adjust to the manufacturer’s specification.

5. Air Intake System Check

Sub-steps:
1. Inspect the air filter and replace if it is dirty or clogged.
2. Check for any vacuum leaks in hoses and connections, repairing or replacing any damaged components.
3. Clean the mass air flow (MAF) sensor with appropriate cleaner if present.
