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 for safety.

2. Fuel System Inspection

Check Fuel Pump:
- Locate the fuel pump relay and test it with a multimeter.
- If faulty, replace the fuel pump relay.
Inspect Fuel Filter:
- Remove the fuel filter according to the manufacturer’s specifications.
- Replace if clogged or damaged.

3. Ignition System Repair

Replace Spark Plugs:
- Remove the ignition coils to access the spark plugs.
- Use a spark plug socket to remove old plugs and install new ones (torque to manufacturer's specification).
Inspect and Replace Ignition Coils:
- Check each ignition coil for cracks or damage.
- Replace any faulty coils.

4. Throttle Body Cleaning

Remove Throttle Body:
- Disconnect the throttle body connector and any hoses attached.
- Unbolt the throttle body from the intake manifold.
Clean Throttle Body:
- Use throttle body cleaner and a soft brush to clean the inside surfaces.
- Reinstall throttle body and reconnect all components.

5. Battery and Alternator Check

Test Battery Voltage:
- Use a multimeter to check the battery voltage (should be around 12.6 volts).
- Replace the battery if voltage is low.
Check Alternator Output:
- Start the engine and measure voltage at the battery with the engine running (should be between 13.7 to 14.7 volts).
- Replace alternator if output is out of range.
