Problem Description and Possible Solution
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.

The check engine light has been on and off for several years now. I had no idea that it may be something faulty until I read this notice about PCV Grommet Vacuum Leaks while checking for recalls on my 1993 Lincoln Mark VIII.
I never received a recall notice for any problem with my vehicle and am unsure as to who should be contacted about this problem.
