Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical shorts during repair.

2. Check and Replace Spark Plugs

• Tools Required: Socket set, torque wrench, spark plug socket
• Remove the ignition coils or spark plug wires to access the spark plugs.
• Use a spark plug socket to remove the old spark plugs.
• Inspect for signs of damage or incorrect heat range.
• Install new spark plugs, ensuring they are gapped correctly as per the manufacturer's specifications.
• Torque the spark plugs to the manufacturer's recommended settings.

3. Fuel System Inspection and Cleaning

• Tools Required: Fuel pressure gauge, fuel injector cleaner
• Check fuel pressure with a gauge to ensure it meets specifications.
• If pressure is low, inspect the fuel filter and pump for issues and replace as necessary.
• Use a fuel injector cleaner to clean the injectors if they are dirty.

4. Timing Adjustment

• Tools Required: Timing light, socket set
• Refer to the service manual for the correct timing specifications.
• Use a timing light to check the ignition timing; adjust if necessary by loosening the distributor clamp and rotating it to the correct position.

5. Compression Test
