why is my Genesis G70 stalling while driving

Solution

1. Preparation

• Gather tools and parts required for repairs.
• Ensure the vehicle is parked on a flat surface and the engine is turned off.
• Disconnect the battery to ensure safety during electrical component handling.

2. Fuel System Inspection

1. Check Fuel Pump:

   • Locate the fuel pump access panel (if applicable) or remove the rear seat to access the fuel pump.
   • Use a multimeter to test the fuel pump's voltage. It should be around 12 volts when the ignition is on.
   • If no voltage is present, check the fuel pump relay and fuses.

2. Replace Fuel Filter (if necessary):

   • Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
   • Disconnect the fuel lines from the filter, using a line wrench.
   • Replace the filter with a new one, ensuring correct orientation.
   • Reconnect fuel lines and restore fuel pressure.

3. Ignition System Repair

1. Inspect Spark Plugs:

   • Remove the ignition coils using a socket set.
   • Check the condition of the spark plugs for wear or carbon buildup. Replace if necessary.
   • Ensure the gap is set to the manufacturer’s specifications.

2. Replace Ignition Coils (if faulty):

   • If the coils are damaged, replace them with new units.
   • Reinstall the coils and ensure they are seated properly.

4. Throttle Body Cleaning

1. Remove Throttle Body:

   • Disconnect the intake ducting and electrical connectors.
   • Remove the throttle body mounting bolts using a socket set and carefully detach it.

2. Clean Throttle Body:

   • Use throttle body cleaner and a soft brush to clean the throttle plate and intake passages.
   • Ensure no residue is left inside the throttle body.

3. Reinstall Throttle Body:

   • Reattach the throttle body and secure it with bolts.
   • Reconnect all electrical connectors and intake ducting.
