clogged catalytics converters
well the cats on my 97 expy 5.4 are clogged. i put one on because thats all could afford for now and it made it alot better. well now its back the way it was after only a couple days. theres gotta be something wrong with the engine causing it to burn up the cats. is there any common problems???
