Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fuel pressure gauge, cleaning supplies.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to avoid electrical shorts during inspection.

2. Inspect and Clean Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner into the throttle body and wipe clean with a lint-free cloth.
Open the throttle plate manually to clean the inside thoroughly.
Reinstall the air intake duct securely.

3. Check and Replace Ignition Components

Remove the engine cover if applicable.
Inspect the spark plugs for wear; replace if necessary (use OEM specifications for gap).
Test ignition coils using a multimeter; replace any faulty coils.
Reinstall the engine cover.

4. Inspect and Replace Fuel Filter

Locate the fuel filter in the fuel line.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter and remove it using a socket set.
Install a new fuel filter, ensuring correct orientation and secure connections.
Reinstall the fuse and prime the fuel system.

5. Test and Replace MAF Sensor

Disconnect the MAF sensor connector.
Use a multimeter to check the sensor voltage according to manufacturer specifications.
If the MAF sensor is faulty, replace it with a new unit and reconnect the wiring.
