my Honda Civic 9th Generation (2012-2015) won't accelerate, what should I do?

Solution

1. Preparation

• Gather tools and parts needed for repair.
• Disconnect the negative battery terminal to ensure safety.
• Allow the engine to cool before starting work.

2. Clean the Throttle Body

• Remove the air intake duct to access the throttle body.
• Use throttle body cleaner and a soft cloth to clean the throttle body and remove carbon deposits.
• Reinstall the air intake duct securely.

3. Inspect and Replace Fuel Filter

• Locate the fuel filter in the fuel line (consult service manual for location).
• Disconnect the fuel lines using the appropriate tools, taking care to avoid fuel spillage.
• Replace the old fuel filter with a new one, ensuring proper orientation.
• Reconnect the fuel lines and check for leaks before starting the engine.

4. Replace Spark Plugs

• Remove the ignition coils by unscrewing the retaining bolts and disconnecting electrical connectors.
• Use a spark plug socket to remove old spark plugs.
• Install new spark plugs, ensuring they are gapped correctly (refer to specifications).
• Reinstall the ignition coils and secure them with bolts.

5. Check and Replace Transmission Fluid (if necessary)

• Locate the transmission dipstick and check fluid level and condition.
• If fluid is low or dirty, drain the old fluid by removing the drain plug.
• Replace with manufacturer-recommended fluid, filling it to the proper level.
• Start the engine and cycle through the gears to circulate the new fluid.
