Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before beginning work.

2. Inspect and Replace Air Filter

Remove the air intake duct to access the air filter.
Inspect the air filter for dirt and debris. If dirty, replace it with a new one.
Reassemble the air intake duct and secure it properly.

3. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter according to the service manual.
Use a line wrench to disconnect the fuel lines (ensure fuel pressure is relieved first).
Replace the old fuel filter with a new one, tightening fittings securely.

4. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean any carbon buildup around the throttle plate.
Reassemble all components securely.

5. Inspect and Replace Spark Plugs

Remove the ignition coil or spark plug wires to access 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 manufacturer specifications.
Reconnect ignition coils or spark plug wires.

6. Test Drive

Reconnect the negative battery terminal.
Start the engine and allow it to idle.
Conduct a test drive, monitoring for power loss during uphill driving.
