my Skoda Octavia NFL (2020-Present) has poor acceleration, what could be the cause?

Solution

1. Preparation

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

2. Fuel System Inspection

1. Check Fuel Pressure

   • Connect a fuel pressure gauge to the fuel rail.
   • Turn the ignition on (do not start the engine) and observe the reading. It should match the manufacturer's specifications.
   • If low, inspect the fuel pump, filter, and lines for blockages or failure.

2. Replace Fuel Filter (if necessary)

   • Locate the fuel filter under the vehicle or in the engine bay.
   • Use a wrench to disconnect the fuel lines, taking care to catch any spilled fuel.
   • Remove the old filter and install the new one, ensuring proper orientation.

3. Air Intake System Cleaning

1. Inspect and Clean the Air Filter

   • Remove the air filter housing cover.
   • Take out the air filter and inspect for dirt or damage. Replace if necessary.
   • Clean the air filter housing with a damp cloth.

2. Throttle Body Cleaning

   • Remove the intake duct connected to the throttle body.
   • Spray throttle body cleaner onto a cloth and wipe the throttle plate until clean.
   • Reassemble the intake duct securely.

4. Ignition System Check

1. Inspect Spark Plugs

   • Remove the spark plugs using a socket wrench.
   • Inspect for wear, carbon buildup, or damage. Replace if necessary.
   • Torque the new spark plugs to the manufacturer's specification (usually around 15-20 Nm).

2. Check Ignition Coils

   • Remove the ignition coils by unclipping and pulling them out.
   • Inspect for cracks or carbon tracking. Replace faulty coils.

5. Transmission Fluid Check

1. Inspect Transmission Fluid
   • Remove the transmission dipstick (if applicable) and check fluid level and condition (should be reddish and clear).
   • If low, add the appropriate transmission fluid as specified by the manufacturer.
