Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Air Filter

Locate the air filter housing (usually near the engine) and unclip or unscrew the cover.
Remove the old air filter and inspect for dirt and debris.
Install a new air filter, ensuring it fits snugly in place.
Reattach the air filter housing cover securely.

3. Clean Throttle Body

Locate the throttle body, typically connected to the intake manifold.
Remove the intake duct by loosening the clamps and disconnecting any sensors.
Use throttle body cleaner and a soft cloth to wipe the interior surfaces of the throttle body.
Reconnect the intake duct and sensor connections securely.

4. Inspect Spark Plugs

Remove the ignition coil packs or plug wires (whichever is applicable) to access the spark plugs.
Use a spark plug socket and ratchet to remove the spark plugs.
Inspect each spark plug for signs of wear or fouling; replace if necessary.
Gap the new spark plugs to the manufacturer's specifications and install them.

5. Check Battery and Charging System

Use a multimeter to test the battery voltage; it should be around 12.6 volts at rest.
Start the engine and check the voltage again; it should read between 13.7 to 14.7 volts when running.
If the voltage is outside this range, consider replacing the alternator or battery as needed.
