Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Air Filter

Locate the air filter housing.
Open the housing and remove the old air filter.
Install a new air filter, ensuring it is seated properly and secured in place.

3. Replace Spark Plugs

Remove the ignition coil or spark plug wires from the spark plugs.
Use a socket set to unscrew and remove the old spark plugs.
Inspect the gap on the new spark plugs and adjust if necessary.
Install the new spark plugs and reconnect the ignition coils or spark plug wires.

4. Clean or Replace Fuel Injectors

If cleaning, use a fuel injector cleaning kit following the manufacturer's instructions.
If replacing, disconnect the fuel lines and electrical connectors from the injectors.
Remove the old injectors and install new ones, ensuring proper orientation and seal.

5. Check Tire Pressure

Use a tire pressure gauge to check the pressure of all tires.
Inflate tires to the manufacturer's recommended pressure levels.
Inspect tires for uneven wear or damage and replace if necessary.
