oxygen sensor switching help
i'm getting a bank 1 sensor 1 and bank 2 sensor 1 heated oxygen sensor insuffient switching code. i did h/c header install a couple months ago and everything was fine and no codes until yesterday. one sensor was brand new at time of header install. and was fine till yesterday. i bought a new sensor yesterday and put it on. still got the code so then i switched sides and still getting code. so in short one sensor is brand new and one sensor is two months old. any suggestions?

If it's bugger cold in "Horsepower Central" then the O2
sensors just will have a even harder time of making
operating temp, let alone quick enough to satisfy the
PCM test.
Insufficient switching is one of those "heat" type codes
that we just have to kill, to run headers without it
bitching. But recognize that this also indicates low-end
closed loop mixture quality problems headed your way.
