Solution

1. Preparation

Gather tools: OBD-II scanner, tire pressure gauge, socket set, multimeter, and basic hand tools.
Ensure safety by disconnecting the battery before working on electrical components.

2. Address Error Codes

If diagnostic codes indicate specific issues (e.g., O2 sensor failure), replace the faulty parts.
- Disconnect the battery.
- Locate and remove the faulty O2 sensor using a socket wrench.
- Install the new sensor and reconnect the battery.

3. Check and Replace Air Filter

Remove the air filter housing cover.
Take out the old air filter and inspect for dirt or blockages.
Install a new air filter and securely close the housing.

4. Inspect and Clean Fuel System

Check for fuel leaks in the fuel lines and connections.
If injectors are clogged, use a fuel injector cleaning kit:
- Disconnect the fuel injectors and follow the instructions to clean them.
- Reinstall the cleaned injectors.

5. Replace Spark Plugs

Remove the ignition coils and spark plug wires.
Use a socket wrench to remove old spark plugs.
Check the gap on new spark plugs as per manufacturer specifications.
Install new spark plugs and reconnect ignition components.
