Okay so my check engine light goes on here and there and goes away i pulled the codes here they are. My mechanic friend said it seems to be a clogged cat on the driver side which should be covered because cats i believe i have a 130,000km with lincoln. Here are the codes... what you guys think. Also My buddy told me to go to the hwy and go at high rpm's and let go off gas not hit brake but let it coast, that usually clean out the cat he said. Any other recommendations?
