Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repair.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Clean Throttle Body

Tools Required: Throttle body cleaner, socket set, screwdriver.
Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle body, especially around the throttle plate.
Reattach the air intake duct securely.

3. Inspect and Test Fuel System

Tools Required: Fuel pressure gauge.
Locate the fuel pressure test port on the fuel rail.
Connect the fuel pressure gauge and turn the ignition to the ON position without starting the engine.
Check the fuel pressure reading. It should be within the manufacturer's specified range. If out of range, check the fuel pump and filter.

4. Inspect Ignition Components

Tools Required: Socket set, multimeter.
Remove the ignition coils from the engine.
Check the spark plugs for wear and replace if necessary.
Use a multimeter to test the resistance of the ignition coils. Replace any faulty coils.

5. Check Battery and Alternator

Tools Required: Multimeter.
With the engine running, use a multimeter to check the voltage at the battery terminals. It should read between 13.5-14.5 volts.
If the voltage is too low, test the alternator and battery condition. Replace as needed.
