Is the check engine light on while it's running ? If so the MIL 'command status' should be 'on'. BOTH indicate a problem in your emissions system , of which you might not notice because your engine may be running 'fine' to the feeling , but something is wrong with what's coming out of your tailpipe . Need codes to help further.
