why does my Genesis G70 have weak acceleration after maintenance

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the battery to ensure safety during electrical inspections.
• Allow the engine to cool down if it has been running recently.

2. Inspect Air Intake System

• Remove the air intake duct and inspect for any loose connections or damage.
• Clean the air filter or replace it if it is dirty or clogged.
• Reinstall the air intake duct ensuring a secure fit.

3. Check Throttle Body

• Remove the throttle body from the intake manifold.
• Clean the throttle body with throttle body cleaner and a soft brush to remove carbon buildup.
• Inspect the throttle position sensor for proper operation and alignment.
• Reinstall the throttle body, ensuring all bolts are tightened to the manufacturer’s torque specifications.

4. Verify Fuel System

• Connect a fuel pressure gauge to the fuel rail test port.
• Start the engine and check the fuel pressure against the manufacturer’s specifications.
• If pressure is low, check the fuel filter and fuel pump for proper operation. Replace as necessary.
• Reconnect any fuel lines or components that may have been disturbed during maintenance.

5. Check for Vacuum Leaks

• Visually inspect all vacuum hoses for cracks or disconnections.
• Use a smoke machine or soapy water to identify any leaks around the intake manifold and hoses.
• Replace any damaged hoses and ensure all connections are secure.
