Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect it. If dirty, replace it with a new air filter.
Reassemble the air filter housing cover securely.

3. Check and Replace Fuel Filter

Locate the fuel filter (usually along the fuel line).
Relieve the 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 wrench.
Replace the old filter with a new one, ensuring correct orientation, and reconnect the fuel lines.

4. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Spray throttle body cleaner onto a clean cloth and wipe the throttle plate and inside of the throttle body to remove carbon buildup.
Reassemble the intake duct securely.

5. Check and Replace Spark Plugs

Remove the ignition coil(s) by unscrewing them with a socket set.
Take out the spark plugs using a spark plug socket.
Inspect the condition of the spark plugs; replace any that show signs of wear or fouling.
Reinstall new spark plugs and reattach the ignition coils.

6. Transmission Fluid Check

Locate the transmission dipstick (if applicable).
Pull the dipstick out, wipe it clean, and reinsert it to check the fluid level.
If low, add the correct type of transmission fluid as specified in the owner’s manual.
