spudley1988 Posted March 21, 2013 Share Posted March 21, 2013 Does anyone know why my car seems to be de-catting itself? I think emissions could be iffy but why would this be occuring. could things like lambda sensor be fluffing it up. I have a cat in the centre section from a 1.4 EJ civic as i changed my manifold which decatted it so I threw a EJ one into centre section. Surely the different cat would still do as good a job? Any help would be appreciated because not looking forward to buying a new cat Quote Link to comment Share on other sites More sharing options...
