Solution

1. Preparation

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

2. Replace Spark Plugs

Tools Required: Spark plug socket, ratchet, torque wrench.
Sub-steps:
1. Remove the engine cover if applicable to access the spark plugs.
2. Using a spark plug socket, carefully unscrew each spark plug from the cylinder head.
3. Inspect the old spark plugs for wear. Replace them with new, manufacturer-recommended spark plugs.
4. Torque the new spark plugs to the manufacturer specification (usually around 15-20 lb-ft).
5. Reattach the ignition coils and any connectors removed.

3. Clean or Replace Air Filter

Tools Required: Screwdriver (if necessary).
Sub-steps:
1. Locate the air filter housing and remove the cover.
2. Take out the air filter and inspect it for dirt and debris.
3. If dirty, replace the air filter with a new one. Clean the housing before reinstalling the cover.

4. Inspect and Repair Vacuum Lines

Tools Required: Basic hand tools for removal.
Sub-steps:
1. Visually inspect all vacuum lines under the hood for cracks, breaks, or disconnections.
2. Replace any damaged vacuum lines with new hoses of the same diameter.
3. Ensure all connections are secure.

5. Fuel System Inspection

Tools Required: Fuel pressure gauge.
Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "ON" position (do not start the engine) and check the pressure reading.
3. If pressure is below specifications, further inspect the fuel pump and filter.
4. Replace the fuel filter if necessary and check for any issues with the fuel pump operation.
