Wow deerlick you really need to get a life... all I offered was a suggestion for him to check out, never stated that for him to fix his problem that was all he had to do. I in fact had both of those codes, had $800 worth of service done at a Ford dealership... ie a 150K service check. The codes were cleared but the dealership told me that the cat on bank 2 had "insufficient flow" and the cost to fix it was like $700 for one side. They also told me the code would return. When it did return I took it to a muffler shop for the cat to be replaced and had both sides done to the tune of $600 since I did not desire to have car payments again. 30 days later the codes came back again, I did a little research by google to see if there was info on the codes and came up with that. I can be a pretty decent back yard mechanic if I think I can save some $$$. If fact the $6 I spent on the electrical cleaner seems to be a pretty good investment so far as the code has been gone now for some 1500 miles. I will be sure to incorporate the cleaner into the maintenance I do when the air filter is replaced each time.
