Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Fuel System Inspection

Sub-steps:
1. Locate the fuel rail and connect the fuel pressure gauge.
2. Turn the ignition to the "ON" position (do not start the engine) and check the fuel pressure reading.
3. If the pressure is low, inspect the fuel pump and filter for blockages and replace if necessary.
Tools Required: Fuel pressure gauge, basic hand tools.

3. Throttle Body Cleaning

Sub-steps:
1. Remove the air intake duct from the throttle body.
2. Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
3. Reinstall the duct and reconnect any sensors or components removed.
Tools Required: Throttle body cleaner, soft brush, basic hand tools.

4. Ignition System Replacement

Sub-steps:
1. Remove the engine cover (if applicable).
2. Disconnect the ignition coils from the wiring harness and remove them from the spark plugs.
3. Replace spark plugs with new ones, ensuring the gap is set according to manufacturer specifications.
4. Reinstall the ignition coils and reconnect the wiring.
Tools Required: Socket set, torque wrench.
Torque Values: Spark plug torque should be set to 13 lb-ft (17.5 Nm).

5. Battery and Charging System Check

Sub-steps:
1. Use a multimeter to measure battery voltage; it should read around 12.6 volts or more.
2. Start the vehicle and measure the voltage again; it should read between 13.7 to 14.7 volts.
3. If readings are outside this range, test the alternator and replace if faulty.
Tools Required: Multimeter.
