Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety.
Allow the engine to cool down before starting the work.

2. Clean or Replace the Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and visually inspect it for dirt and damage.
If dirty, replace it with a new air filter; if reusable, clean it with compressed air.

3. Inspect and Clean the Throttle Body

Remove the throttle body from the intake manifold (if applicable).
Use throttle body cleaner and a soft cloth to remove carbon buildup.
Reinstall the throttle body, ensuring all gaskets are intact.

4. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter along the fuel line.
Use wrenches to disconnect the fuel lines carefully (be cautious of fuel spray).
Replace the old fuel filter with a new one, ensuring proper orientation.

5. Test and Replace Spark Plugs

Remove the ignition coils using a socket set.
Take out the spark plugs with a spark plug socket and inspect for wear.
Replace with new spark plugs, ensuring proper torque (typically 13-15 lb-ft).

6. Transmission Fluid Check

Locate the transmission dipstick and check the fluid level.
If low, add the recommended transmission fluid (refer to owner's manual).
If fluid is burnt or discolored, consider a transmission fluid change.
