Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the vehicle's battery to avoid electrical issues during repairs.

2. Inspect and Replace Fuel Filter

Locate the fuel filter in the fuel line.
Use the appropriate socket to disconnect the fuel lines carefully (use safety glasses).
Remove the fuel filter and replace it with a new one.
Reconnect the fuel lines ensuring no leaks.

3. Test and Replace Spark Plugs

Remove the engine cover if applicable.
Use a spark plug socket to remove the spark plugs.
Inspect for wear, carbon build-up, or damage.
Replace with OEM spark plugs, ensuring to torque them to the manufacturer's specifications (typically around 13-15 lb-ft).
Reinstall the engine cover.

4. Check and Replace Battery

Inspect the battery terminals for corrosion and ensure a tight fit.
If the battery voltage is low (below 12.4 volts), remove it using a wrench.
Replace with a new battery of the same specifications.
Reconnect the terminals and ensure they are secured.

5. Update Engine Control Module (ECM)

Connect the OBD-II scanner to the vehicle's diagnostic port.
Follow the manufacturer's instructions to check for ECM updates.
If available, perform the update to ensure optimal engine performance.
