Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Ensure the vehicle is on level ground and secure with wheel chocks.

2. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft brush to clean the inside of the throttle body.
Reinstall the air intake duct and securely fasten it.

3. 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 fuel lines from the filter using a line disconnect tool.
Replace the old filter with a new one, ensuring correct orientation and secure connections.

4. Inspect and Replace Spark Plugs

Remove the ignition coil from each cylinder by unscrewing the bolts and gently pulling them out.
Use a spark plug socket to remove old spark plugs.
Inspect the spark plugs for wear; replace with new plugs if necessary (specify gap according to manufacturer specs).
Reinstall ignition coils and secure with bolts.

5. Check Transmission Fluid

Locate the transmission dipstick and remove it.
Check fluid level; add fluid if low, using the manufacturer-recommended type.
If fluid appears burnt or dirty, consider a complete transmission fluid flush.
