how to troubleshoot Honda Accord 10th Generation (2018-2022) engine hesitation when accelerating

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Allow the engine to cool before beginning work.

2. Clean or Replace Air Filter

• Remove the air filter cover using a socket set.
• Take out the air filter and inspect it for dirt or damage.
• If dirty, replace it with a new OEM air filter; if clean, reinstall it.

3. Test and Replace Fuel Filter (if applicable)

• Locate the fuel filter in the fuel line.
• Use a wrench to disconnect the fuel lines; have a rag ready for any spills.
• Replace the filter with a new one and reconnect the lines securely.

4. Inspect and Replace Spark Plugs

• Remove the ignition coil cover using a socket set.
• Disconnect the ignition coils from the spark plugs.
• Use a spark plug socket to remove the spark plugs and inspect them for wear or fouling.
• Replace with new spark plugs, ensuring correct torque (typically 13-16 lb-ft).

5. Clean Throttle Body

• Remove the air intake duct connected to the throttle body.
• Use throttle body cleaner and a clean rag to wipe down the interior surfaces.
• Reassemble the intake duct securely, ensuring no vacuum leaks.

6. Test and Clean MAF Sensor

• Carefully remove the MAF sensor from the intake manifold.
• Use MAF cleaner spray to clean the sensor elements; do not touch them.
• Reinstall the MAF sensor and ensure all connections are tight.
