my Genesis G70 struggles to accelerate, what's the issue

Solution

1. Preparation

• Gather tools and parts.
• Disconnect the negative battery terminal to ensure safety.

2. Inspect and Clean Air Intake

• Remove the air intake duct and check for obstructions.
• Clean the air filter and replace it if necessary.
• Reinstall the air intake duct securely.

3. Check Fuel Pressure

• Connect the fuel pressure gauge to the fuel rail.
• Turn the ignition to the ON position without starting the engine to check the pressure reading.
• If the pressure is below specifications, replace the fuel pump or filter as needed.

4. Clean Throttle Body

• Remove the throttle body from the intake manifold.
• Use throttle body cleaner and a soft cloth to remove carbon buildup.
• Reinstall the throttle body and ensure all connections are secure.

5. Inspect Ignition System

• Remove spark plugs and inspect for wear or fouling.
• Replace any damaged or worn spark plugs with OEM parts.
• Test ignition coils with a multimeter; replace faulty coils.

6. Check Transmission Fluid

• Locate the transmission dipstick and remove it.
• Check fluid level and condition; the fluid should be bright red and not burnt.
• If low, add the appropriate transmission fluid; if burnt, consider a fluid change and filter replacement.
