Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface, and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Air Filter

Remove the air filter housing cover.
Take out the old air filter and inspect it for dirt and debris.
Install a new, clean air filter (OEM recommended).
Reattach the air filter housing cover securely.

3. Check and Repair Fuel System

Inspect fuel lines for visible leaks or damage.
If leaks are found, replace the damaged sections of the fuel line.
If injectors are faulty, remove and clean or replace them as needed.
Reconnect any disconnected fuel lines and ensure all connections are secure.

4. Replace Spark Plugs

Remove the ignition coils or spark plug wires carefully.
Use a spark plug socket to remove old spark plugs.
Inspect the condition of the spark plugs and replace them with new ones if worn or fouled.
Torque the new spark plugs to manufacturer specifications (typically around 13-15 lb-ft).

5. Check Tire Pressure

Use a tire pressure gauge to check each tire's pressure.
Inflate tires to the manufacturer's recommended pressure (usually found on the driver’s door jamb).
Inspect tires for uneven wear which may indicate alignment issues.
