Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.
Raise the vehicle with a jack and secure it with jack stands.

2. Inspect and Replace Air Filter

Remove the air filter housing cover.
Take out the air filter and visually inspect it for dirt and debris.
If it is dirty, replace it with a new OEM air filter.
Reassemble the air filter housing cover.

3. Check and Replace Fuel Filter

Locate the fuel filter (if applicable, as some models have it integrated with the fuel pump).
Disconnect the fuel lines (ensure to relieve fuel pressure first).
Replace the old fuel filter with a new one.
Reconnect the fuel lines securely.

4. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft brush to clean any carbon buildup.
Ensure the throttle plate moves freely.
Reassemble the air intake duct.

5. Inspect and Replace Spark Plugs

Remove the ignition coils from the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Check the gap on the new spark plugs and install them according to specifications.
Reinstall ignition coils securely.

6. Check Transmission Fluid

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