Solution

1. Preparation

Gather tools: OBD-II scanner, fuel pressure gauge, socket set, torque wrench, cleaning supplies (e.g., throttle body cleaner).
Ensure the vehicle is parked on a level surface, and the engine is cool.

2. Address Error Codes

If error codes are present, document them for troubleshooting.
Clear codes and test drive to see if they return.

3. Replace Air Filter

Locate the air filter housing.
Remove the air filter cover using a socket set.
Take out the old air filter and clean the housing with a damp cloth.
Install a new air filter and reassemble the housing.

4. Test and Replace Spark Plugs

Remove ignition coil covers.
Use a socket set to remove spark plugs and inspect them for wear or fouling.
Replace with new spark plugs, ensuring correct torque specification (typically around 13-15 lb-ft).

5. Clean Throttle Body

Disconnect the battery before working on the throttle body.
Remove the intake duct leading to the throttle body using a socket set.
Spray throttle body cleaner into the throttle body and scrub with a soft cloth to remove buildup.
Reassemble the intake duct and reconnect the battery.

6. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter (check owner's manual for location).
Relieve fuel pressure from the system before removal.
Replace the fuel filter and ensure all connections are tight.
