Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect for dirt and blockages.
Replace with a new air filter if necessary.

3. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter, usually near the fuel tank or engine.
Relieve fuel pressure before removing the filter by disconnecting the fuel pump relay and starting the engine until it stalls.
Remove the old fuel filter using the appropriate wrenches, and install the new filter, ensuring the flow direction is correct.

4. Inspect and Replace Spark Plugs

Remove the ignition coils by unscrewing them from the engine.
Take out the old spark plugs using a spark plug socket.
Check the gap on the new spark plugs and adjust if necessary.
Install the new spark plugs and reattach the ignition coils.

5. Transmission Fluid Inspection and Change

Check the transmission fluid level with the dipstick while the engine is running.
If low, add the recommended transmission fluid.
If the fluid is dirty or burnt, drain the transmission fluid, replace the filter, and refill with fresh fluid.

6. Inspect Exhaust System

Visually inspect the exhaust system for any visible blockages or damage, focusing on the catalytic converter.
If a blockage is suspected, remove the catalytic converter and inspect it for clogs; replace if necessary.
