Report: Check Engine Light Due to PCV Grommet Vacuum Leaks
Lincoln Continental Problem
A vacuum leak from the PCV grommet vacuum leak can cause the Check Engine Light to illuminate. The molded rubber hose connections may crack and collapse, causing the vehicle to run roughly. A damaged PCV hose will require replacement.
