My 2000 civic si has a check engine light on (code 67 catalyst below efficiency) & yet the Vtec still engages everyone says this is impossible. So what's going on any ideas?

 

You need a Cat. V-tec will still work with a check engine light

get an o2 sim and slap it in there, a casper's one works nice
