Honda CR-V engine pulsating issue during idle and driving on Honda CR-V

Some Honda CR-V owners report experiencing engine pulsating issues, including idle pulsation where the engine revs between 1,000 to 1,500 RPM once warmed up. Many owners also face rough idle, which can be frustrating and potentially dangerous, often attributed to problems with spark plugs and wires that ignite the air-fuel mixture in the engine's cylinders. Additionally, noticeable vibration at idle has been reported, causing discomfort. Some CR-Vs exhibit a stubborn surging idle, leading to a PO505 code being triggered. Common causes of these issues include faulty spark plugs, a cracked air tube, a dirty mass airflow sensor, and problems within the ignition system. To address these concerns, owners are advised to check for vacuum leaks, clean the throttle, and inspect components like the air tube, air filter, and mass airflow sensor to effectively diagnose and resolve engine pulsation problems.
