I have a 2003 V8 explorer, and sometimes when i'm driving, the engine cut, like there is missfire, and when i stop the engine shut off. Then my check engine light come on.

It give me the code p0430, that mean, Catalyst System Efficiency Below Threshold (Bank 2).

But the problem is that is not always doing it. It's a month that i have my truck, he did it twice in the first week, and he always did it again this morning.

I hope some of you guys can help me.
