I have the engine code P0430 on my 2001 Nissan Maxima and engine hesitations

Question

When you get a catalytic converter code like P0430 combined with hesitation, how bad is the problem? I see some of your posts indicate P0430 won't cause driveability problems, but I commute 39 miles one way to my job and any kind of hesitation is of concern to me. However, I've spent thousands on repairs, etc over the last 2 yrs+ yrs on engine light issues on this car (plus tons on other issues like control arms, wheel bearings, etc), and I can't afford ANY repairs - especially ones of this magnitude. The car just passed inspection a month ago.

I bought it in 2009 or 2010 with 65K miles on it. I have since had to have this work done for engine light issues:
mass air flow sensor replaced Apr 2012
May 2012 2Y060 sensor replaced
November 30 2013 I replaced O2 sensors before and after (upper) with gaskets, plus the Rt side Catalyc converter, along with emissions shutoff valve.
March 2014 I replaced coil6 (twice) before replacing all 6 in April (and put a new Nissan gas cap on).
In May 2014 I replaced R&R bypass cut valve for evap leak.

The prior owner had receipts for these engine light issues:
Nov 2006 Ox sensor 226A1-4L715, reprogrammed ECM, Heated Ox sensor 226A0-4L713
Jan 2007 front O2 sensor Heated Ox sensor 22690-2Y921

Answer 1

P0430 usually means the catalytic converter is bad if there are not exhaust leaks or other engine issue. If the car is hesitating it could mean the catalytic converter is clogged up.

If you have to replace the  catalytic converter it is expensive maybe around $1000
