Nissan Juke persistent engine light issue with slow idle and frequent stalling despite airflow sensor replacement on Nissan Juke

Some Nissan Juke owners report experiencing persistent engine light issues, characterized by slow idle and frequent stalling, even after replacing the airflow sensor. These problems may arise from a faulty mass airflow sensor that leads to incorrect air-fuel mixture regulation, resulting in rough idling and poor acceleration. Additionally, common causes for stalling include issues within the fuel system, air intake system, or ignition system, where erroneous signals from the MAF sensor can trigger the check engine light and diagnostic trouble codes. Fuel-related problems, such as contaminated gas or water in the tank, can also contribute to rough running symptoms. To resolve these issues, some owners find it necessary to check the vacuum level, perform an idle re-learn, clean or replace the MAF sensor, adjust the idle, inspect the PCV valve, or consult a mechanic for further assistance.
