Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect and Replace Air Filter

Remove the air filter housing cover.
Take out the old air filter and inspect it for dirt and clogs.
Replace with a new air filter if necessary.
Reassemble the air filter housing securely.

3. Check and Replace Fuel Filter

Locate the fuel filter along the fuel line.
Relieve fuel system pressure before removal.
Disconnect the fuel lines and remove the old fuel filter.
Install a new fuel filter, ensuring proper orientation and secure connections.

4. Inspect and Refill Transmission Fluid

Check the transmission fluid level using the dipstick (if applicable).
If low, add the manufacturer-recommended transmission fluid.
If the fluid is dark or smells burnt, consider a transmission fluid change.

5. Test and Replace Spark Plugs

Remove the ignition coil or spark plug wires.
Extract the spark plugs using a spark plug socket.
Inspect for wear; replace if necessary with OEM-spec plugs.
Reinstall the spark plugs and reconnect the ignition components.
