Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted if needed.
Disconnect the battery negative terminal to ensure safety.

2. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect the ignition coils from the spark plugs.
3. Use a socket set to remove the spark plugs.
4. Inspect plugs for wear; replace with OEM equivalent if needed.
5. Torque the new spark plugs to the manufacturer's specifications (typically around 13-15 lb-ft).

3. Check and Adjust Engine Timing

Sub-steps:
1. Remove any components obstructing access to the timing cover.
2. Use a timing light to check timing marks while the engine is running.
3. If timing is off, consult service manual for adjustment procedures.
4. Reassemble any components removed.

4. Inspect Fuel System

Sub-steps:
1. Use a fuel pressure gauge to check the fuel pressure against manufacturer specifications.
2. If pressure is low, check the fuel filter and replace if necessary.
3. Inspect the fuel pump for proper operation and replace if faulty.

5. Address Vacuum Leaks

Sub-steps:
1. Visually inspect hoses and connections for wear or damage.
2. Use a smoke machine or carburetor cleaner to detect leaks.
3. Replace any damaged hoses or gaskets as needed.
