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.
Check engine light comed on when engine is cold and going up a hill under a load. Does not happen all the time
