Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery before starting any repair work to ensure safety.
Allow the engine to cool down before beginning work on any components.

2. Inspect and Clean the Throttle Body

Remove the air intake duct connected to the throttle body by loosening the clamps.
Use a throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
Reattach the air intake duct securely.

3. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter, usually found along the fuel line.
Use a wrench to disconnect the fuel lines from the filter, being cautious of any residual fuel.
Replace the old fuel filter with a new one, ensuring proper orientation.
Reconnect the fuel lines securely and check for leaks.

4. Battery Testing and Replacement (if health is poor)

Use a multimeter to measure the battery voltage; it should be around 12.6 volts when fully charged.
If the battery voltage is low, remove the battery cables (negative first, then positive) and replace the battery with a new one if needed.
Reconnect the battery cables (positive first, then negative) and ensure they are tight.

5. Check Engine Codes

After repairs, reconnect the OBD-II scanner to check if any new codes have appeared.
Clear any fault codes that were present after resolving the issues.

6. Final Assembly

Double-check all connections and components that were removed or inspected.
Reinstall any protective covers or components that were taken off during the repair process.
