Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal.

2. Fuel System Inspection

Sub-steps:
1. Remove the fuel pump fuse or relay to relieve fuel pressure.
2. Disconnect the fuel lines from the fuel filter and fuel injectors.
  - Tools Required: Fuel line disconnect tool, wrench set.
3. Replace the fuel filter if it is clogged or has not been replaced in accordance with the maintenance schedule.
4. Reconnect the fuel lines and reinsert the fuel pump fuse or relay.

3. Ignition System Check

Sub-steps:
1. Remove the spark plugs using a socket wrench.
  - Tools Required: Socket set, torque wrench.
2. Inspect spark plugs for wear or fouling; replace if necessary.
3. Test ignition coils using a multimeter to check for correct resistance.
4. Replace any faulty ignition coils.

4. Battery and Charging System

Sub-steps:
1. Use a multimeter to check the battery voltage (should be around 12.6 volts).
2. Start the engine and check the voltage at the battery terminals (should be between 13.7 to 14.7 volts).
3. Replace the battery if it does not hold a charge or the voltage is low.
4. Inspect the alternator and connections for any wear or damage.

5. Air Intake and Vacuum System

Sub-steps:
1. Inspect the air filter and replace it if dirty or clogged.
2. Check all vacuum hoses for cracks or disconnections; replace as necessary.
3. Clean the throttle body using an appropriate cleaner and a soft brush.
