my Genesis G70 feels like it’s losing power going uphill what’s wrong

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the battery to ensure safety while working on electrical components.

2. Addressing Fuel System Issues

1. Fuel Pressure Check

   • Connect the fuel pressure gauge to the fuel rail test port.
   • Turn the ignition to the "ON" position without starting the engine to check fuel pressure reading.
   • If pressure is below specifications (consult vehicle manual), proceed to replace the fuel pump.

2. Fuel Pump Replacement

   • Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
   • Disconnect the battery again.
   • Remove the fuel tank as per the manufacturer’s instructions to access the fuel pump.
   • Disconnect electrical connectors and fuel lines from the pump.
   • Install the new fuel pump, reconnect lines, and reassemble the fuel tank.

3. Inspecting and Replacing Ignition Components

1. Spark Plug Inspection

   • Remove spark plug wires using a spark plug socket.
   • Inspect each spark plug for wear, deposits, or damage. Replace if necessary.
   • Reinstall spark plugs to specified torque (usually between 10-15 ft-lbs).

2. Ignition Coil Replacement

   • If coils show signs of damage, remove them from the spark plugs.
   • Install new ignition coils and ensure they click into place.

4. Exhaust System Check

• Inspect the catalytic converter for signs of blockage or damage.
• If blockage is suspected, replace the catalytic converter following the manufacturer's guidelines.
