why does my Genesis G70 stall while driving

Solution

1. Preparation

• Gather the necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Fuel System

• Sub-steps:
  1. Connect a fuel pressure gauge to the fuel rail.
  2. Turn the ignition to the "ON" position (without starting the engine) to check the pressure.
  3. Compare the reading with the manufacturer specifications (typically around 50-60 psi for most vehicles).
  4. If pressure is low, inspect the fuel pump and filter for clogs or failures.

3. Check Spark Plugs and Ignition Coils

• Sub-steps:
  1. Remove the ignition coil cover (if applicable) and disconnect the ignition coils.
  2. Inspect each spark plug for wear, carbon buildup, or damage.
  3. Replace any faulty spark plugs with the manufacturer-recommended type.
  4. Test the ignition coils with a multimeter to ensure proper resistance. Replace any that are out of specification.

4. Inspect Air Intake System

• Sub-steps:
  1. Visually inspect the air filter for dirt and blockage; replace if necessary.
  2. Check the intake hoses for cracks or loose connections.
  3. Clean the throttle body using throttle body cleaner to remove carbon buildup.

5. Verify Electrical System

• Sub-steps:
  1. Use a multimeter to check the battery voltage; it should read around 12.6 volts.
  2. Inspect battery terminals and cables for corrosion or loose connections. Clean and tighten as needed.
  3. Perform a charging system test to ensure the alternator is functioning properly, outputting around 13.5-14.5 volts while running.
