Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Replace Air Filter

Locate the air filter housing.
Open the housing by releasing the clips or removing screws.
Remove the old air filter and clean the housing with a soft cloth.
Install the new air filter, ensuring it fits snugly.
Reassemble the housing and secure it.

3. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter based on the vehicle's service manual.
Relieve fuel system pressure by removing the fuse for the fuel pump and starting the engine until it stalls.
Disconnect the fuel lines from the filter using a line wrench to avoid damage.
Remove the old fuel filter and replace it with a new one, ensuring the flow direction is correct.
Reconnect the fuel lines and restore the fuse.

4. Clean Throttle Body

Locate the throttle body and remove the air intake duct.
Use throttle body cleaner and a soft brush to clean the inside of the throttle body.
Inspect the throttle plate for smooth operation; if it sticks, replace the throttle body.
Reassemble the air intake duct.

5. Replace Spark Plugs

Remove the ignition coils by unscrewing the bolts and carefully pulling them out.
Use a spark plug socket to remove the old spark plugs.
Inspect the new spark plugs for proper gap and install them.
Reinstall the ignition coils and secure them with bolts.

6. Test Mass Airflow Sensor (if faulty)

Disconnect the electrical connector from the MAF sensor.
Use a multimeter to measure the voltage output while revving the engine; compare the readings to manufacturer specifications.
If readings are outside specifications, replace the MAF sensor with a new one.
Reconnect the electrical connector.
