Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Air Filter

Remove the air filter housing cover using a screwdriver or socket set.
Take out the old air filter, inspecting it for dirt and debris.
Install a new air filter, ensuring it is seated properly.
Reattach the air filter housing cover and tighten screws.

3. Inspect and Replace Spark Plugs

Locate the spark plug wires and carefully disconnect them.
Use a socket wrench to remove the old spark plugs.
Check electrode condition and replace with new spark plugs as needed, following the manufacturer's specified gap.
Reconnect the spark plug wires securely.

4. Fuel System Inspection

Inspect fuel lines and connections for leaks; replace any damaged components.
Use a fuel pressure gauge to test the fuel pressure against manufacturer specifications.
If pressure is low, consider replacing the fuel pump or fuel filter.

5. Tire Maintenance

Check each tire's pressure using a tire pressure gauge.
Inflate tires to the manufacturer's recommended PSI, adjusting as necessary.
Inspect tires for uneven wear, and replace if necessary.
