Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery before working on electrical components.

2. Fuel System Inspection

Check Fuel Pump Operations:
- Locate the fuel pump relay and verify its function with a multimeter.
- If faulty, replace the fuel pump relay.
Inspect Fuel Filter:
- Disconnect the fuel lines from the fuel filter.
- Replace the fuel filter if clogged.

3. Ignition System Repair

Inspect and Replace Spark Plugs:
- Remove the ignition coil cover.
- Use a socket set to remove old spark plugs and replace them with new ones.
- Torque to manufacturer specifications (typically 13-15 lb-ft).
Check Ignition Coils:
- Test each ignition coil with a multimeter for proper resistance.
- Replace any faulty ignition coils.

4. Battery and Charging System Check

Test Battery Voltage:
- Connect a multimeter to the battery terminals.
- A healthy battery should read around 12.6 volts. Replace if below 12.4 volts.
Inspect Alternator Output:
- Start the engine and check the alternator output; it should be between 13.7 to 14.7 volts.

5. Air Intake and Throttle Body Cleaning

Inspect Air Intake:
- Remove the air intake duct and visually check for blockages.
- Clean or replace any clogged air filters.
Throttle Body Cleaning:
- Remove the throttle body from the engine.
- Use throttle body cleaner and a soft cloth to clean the intake valves. Reinstall.
