Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Clean Air Intake

Remove the air intake duct.
Inspect the air filter for dirt or clogging; replace if necessary.
Clean the throttle body using a throttle body cleaner and a soft cloth.
Reassemble the air intake duct and ensure all connections are secure.

3. Check and Replace Fuel Filter

Locate the fuel filter in the fuel line.
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter using a line removal tool.
Replace the old filter with a new one and reconnect the fuel lines securely.

4. Test and Replace Spark Plugs

Remove the ignition coils using a socket set.
Extract the old spark plugs with a spark plug socket.
Check gap and condition; replace with OEM or equivalent plugs if worn.
Reinstall the spark plugs and ignition coils.

5. Inspect Transmission Fluid

Remove the transmission dipstick and check fluid level.
If low, add the manufacturer-approved transmission fluid until the correct level is reached.
If the fluid is dark or has a burnt smell, consider a transmission fluid change.
