both my cars threw p0420 in same week wtf
I know its for bad cat but its pretty crappy when both of them pop up in same week
Can anything else cause this code to show up?
Bad tank of gas? cold temps or high humidity?
I cleared them and they havent shown up again
My integra threw o2 heater code first then slow responce code and then p0420
But once cleared they never show up again
Both cars have brand new ntk and denso sensors not universal and both are running good besides that

cold temps CAN do it. cats work by getting super hot, if they dont get hot enough they dont work anywhere near as well.
larger diameter exhaust systems and/or placing the cat further from the engine than stock location will also reduce the cat's efficiency due to heat.
