Possible cure.... Remove the mass air flow sensor from air intake tube and spray the element itself with mass air flow sensor cleaner allow to dry and reinstall. hope this helps. USE ONLY MASS AIRFLOW SENSOR CLEANER..Nothing else like carb or fuel injector cleaner. A can of this costs approx. $9.00.
