i have a2001 infiniti i30 it has afault code p0430/what is wrong whit my car
Optional Information: 2001 i30t
That is a catalytic converter code, and it's indicating that your converter that is nearest to your manifold is beginning to fail. There is a service bulletin regarding an engine computer reprogramming that may be necessary if you haven't had it done already. Likewise, this is not an inexpensive repair, but not something critically wrong as long as it's addressed very shortly.
