Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery for safety.
Ensure the vehicle is parked on a level surface.

2. Scan for Error Codes

Use an OBD-II scanner to retrieve any stored trouble codes.
Document any codes that are present for further analysis.

3. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and clean the housing if necessary.
Install a new air filter, ensuring it fits snugly and securely.

4. Clean Throttle Body

Remove the throttle body from the intake manifold using a socket set.
Spray throttle body cleaner onto a clean cloth and wipe the interior surfaces.
Reinstall the throttle body, tightening bolts to the manufacturer’s torque specifications.

5. Inspect and Replace Spark Plugs

Remove the ignition coil using a socket set.
Extract the spark plug with a spark plug socket and inspect for wear or damage.
Replace with new spark plugs according to manufacturer specifications.
Reassemble the ignition coil.

6. Check Fuel Pressure

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the ON position without starting the engine and observe the pressure reading.
If pressure is low, inspect the fuel pump and fuel filter for replacement.
