97 Expedition error code P0430
I have a 97 expedition and a freind of mine came over and hooked up a obd code reader on it. The error code P0430 came up. Can anyone tell me if there is a common problem that causes the engine to sputter occasionally it doesn't do it all of the time but it does it enough. I looked up the code and it told me that it could be anything from bad sparkplugs to a bad exhaust system. Hopefully theres a common problem that others may have had. Any help would be appreciated.
