Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Fuel System

Inspect Fuel Pump:
- Use a fuel pressure gauge to check the fuel pump's output pressure (should be within manufacturer specifications).
- Replace the fuel pump if pressure is below specifications.
Replace Fuel Filter:
- Disconnect the fuel lines and remove the old fuel filter.
- Install a new fuel filter, ensuring proper orientation.

3. Check Ignition System

Inspect Spark Plugs:
- Remove the spark plug wires and check each plug for wear or carbon buildup.
- Replace any worn plugs with new ones, ensuring proper gap settings.
Test Ignition Coils:
- Use a multimeter to check resistance on ignition coils.
- Replace any faulty ignition coils.

4. Examine Battery and Charging System

Check Battery Voltage:
- Use a multimeter to measure battery voltage (should be around 12.6V with the engine off).
- Clean battery terminals and apply anti-corrosion grease if necessary.
Test Alternator:
- Start the engine and measure voltage at the battery; it should be between 13.7V and 14.7V.
- Replace the alternator if it does not output the correct voltage.

5. Clean Throttle Body

Remove Throttle Body:
- Disconnect the air intake hose and throttle position sensor wiring.
- Unbolt and remove the throttle body from the intake manifold.
Clean Throttle Body:
- Use throttle body cleaner and a soft brush to remove carbon buildup.
- Reinstall the throttle body and reconnect all components.
