is it a clogged cat?
So my check engine light is on, went to autozone they did the reader thing with the codes, turns out to be a clogged cat, atleast thats what the code says. Im having no running issues, im getting the same mpg, there isnt any kind of a smell and there is pressure comming out the back tail light? I already tried reseting it and it came back on for clogged cat. is it possible the cats clogged even though im not experiencing any symptons of if
