Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, multimeter, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery to prevent any electrical shorts.

2. Clean or Replace Air Filter

Locate the air filter housing and remove the screws or clips.
Take out the air filter and inspect for dirt and debris.
Clean the housing with a damp cloth. If the air filter is clogged, replace it with a new one.

3. Test and Replace Fuel Pump or Filter

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position (do not start the engine) and check the pressure reading. It should match the specifications in the service manual.
If the pressure is low, inspect the fuel filter for clogs and replace it if necessary.
If the filter is fine, replace the fuel pump according to the manufacturer's specifications.

4. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
Reattach the intake duct and ensure all clamps are secure.

5. Inspect and Replace Spark Plugs and Coils

Remove the engine cover if applicable.
Disconnect the ignition coil connectors and remove the coils.
Remove the spark plugs using a spark plug socket. Inspect for wear, carbon buildup, or damage.
Replace with new spark plugs and coils as per manufacturer specifications. Torque plugs to the correct specification.

6. Check and Replace MAF Sensor (if necessary)

Disconnect the MAF sensor connector and remove it from the intake duct.
Clean the sensor with MAF cleaner. If the issue persists, replace the sensor with a new one.
