Solution

1. Preparation

Gather tools and parts required.
Disconnect the negative battery terminal to prevent electrical shock during repairs.

2. Inspect and Replace Battery

Tools Required: Multimeter, socket set
Sub-steps:
1. Use the multimeter to measure the battery voltage; it should be above 12.4 volts.
2. If the voltage is low, charge or replace the battery.
3. Remove the old battery using a socket set and install the new battery, ensuring to connect the positive terminal first, followed by the negative.

3. Fuel System Inspection

Tools Required: Fuel pressure gauge
Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "ON" position (without starting the engine) to check for fuel pressure.
3. If the pressure is below specifications (check manufacturer specifications), replace the fuel pump or filter as necessary.

4. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the engine cover (if applicable) to access the spark plugs.
2. Use the socket set to remove the spark plugs and inspect for signs of wear or fouling.
3. Replace with new spark plugs, ensuring to torque them to manufacturer specifications.

5. Check Air Intake System

Tools Required: Screwdriver set
Sub-steps:
1. Remove the air intake duct and filter.
2. Inspect the air filter for dirt and clogs; replace if necessary.
3. Clean the air intake duct and reinstall all components securely.
