Disconnect the battery to avoid any electrical issues during repairs.

2. Inspect and Replace Air Filter

Locate the air filter housing (typically near the engine).
Open the housing and remove the old air filter.
Inspect the filter for dirt and debris; replace it with a new one if necessary.
Reassemble the housing securely.

3. Test and Replace Spark Plugs

Remove the ignition coil connectors and unscrew the coils.
Extract the spark plugs using a spark plug socket.
Inspect the spark plugs for wear or carbon buildup; replace if necessary.
Install new spark plugs and reconnect the ignition coils.

4. Clean Fuel Injectors

Use a fuel injector cleaning kit or professional cleaning service.
Disconnect the fuel line from the injectors and attach the cleaning kit.
Follow the manufacturer’s instructions to clean the injectors thoroughly.
Reconnect the fuel line securely and check for leaks.

5. Tire Pressure and Alignment Adjustment

Check the tire pressure using a tire gauge; inflate to manufacturer-recommended levels.
Inspect wheel alignment and adjust if necessary using an alignment tool.
Rotate tires if uneven wear is detected.
