Hey all, My girlfriend's 97 Honda Civic failed her emissions test
today. She passed everything except HC ppm at 40 km/h. The limit was
75, and the car blew 177, interestingly the car blew 177 at idle as
well.

Her regular Honda mechanic is recomending an engine flush. Good idea?

One more thing. As it turns out Hondas had a recall on their Cat's on
this model because of cracking. As it turns out the cat may indeed be
cracked. She's past the recall period but bought her car used from
Honda. Do they have some responsibility to have done recall work on
the used cars they sell?
