Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuel Filter

Locate the fuel filter in the fuel line.
Use appropriate tools to disconnect the fuel lines from the filter.
Remove the old fuel filter and install a new one, ensuring correct orientation.
Reconnect the fuel lines and check for leaks.

3. Clean or Replace Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft brush to clean any carbon deposits.
If damaged or excessively dirty, replace the throttle body with a new unit.
Reattach the air intake duct.

4. Test and Replace Spark Plugs

Remove the ignition coils to access the spark plugs.
Inspect the spark plugs for wear; replace if necessary with OEM specifications.
Reinstall ignition coils securely, ensuring proper connection.

5. Check Transmission Fluid

Locate the transmission dipstick and remove it to check fluid level.
If low, add the appropriate transmission fluid as specified in the owner’s manual.
If the fluid is dirty or burnt, consider a transmission fluid change.
