I got this code twice over the past 3 weeks P0430 Catalyst System Below Threshold (Bank 2). Could my high flow cats be causing this. I got this last week and this morning while on the way to work. I cleared it using the diablo but i was wondering what is the cause of this code?

I get this code now and then as well... I think its related to the O2 sensor readings and the Headers. You might get the Bank1 as well. I only got my codes on really HOT days... now that its cooler out, nothing. I wouldnt worry about it - I cleared mine as well.
Maybe someone else will chime in with an actual answer though...

No biggie if it keeps comming back just get some spark plug antifoulers and screw them in your headers and then the sensor into them it pulls the sensor out of the exhaust path a bit. I was getting it everyday since the weather got cold

I get them 0420/0430 if my rear o2 sensors aren't turned off via predator. Just made a new thread here (http://www.lxforums.com/board/showthread.php?t=143327) to see if a solution worked for those that need to pass emissions.
