CEL galore

CEL galore
Coming up on my annual service luckily as I got the dreaded Emissions Service CEL this weekend, figured maybe I can try and get a jump on a diagnosis, and maybe be able to scope out parts ahead of taking the car in.
All 4 codes popped up at the same time
P2195
P2197
P0171
P0174
A little background, last year about this time I replaced a bad PCV and installed Redpants oil catch can. Also I am decatted and running straight pipes.
Any idea what it could be?

2195 and 2197 are O2 sensor stuck lean. (bank 1 and 2)
0171 and 0172 are system lean. (bank 1 and 2)
I'll PM you a link to an OBD manual that describes troubleshooting procedures.

what's the mileage on the car? You probably need new front O2 Sensors, I had to replace mine with only 30,000km and a lot of people are replacing theirs with 30,000 - 50,000 miles.

I was kindly pointed in this direction for sensors. Hope to get them in the next couple of days.

These O2 sensors are good up-to 2010.5 when they exhaust system was changed to have 2 Cat systems even though they only list 2008 as the later year as I am running them on my 2009 4.7L

28,500. But do I have front O2 sensors if I'm catless?

First, what year is your Vantage... I am sure that you are not catless, you might have the newer exhaust system which has 2 x cats on each side (1 in the header = 200 cells + another one after = 400 cells) I know that a lot of people with that setup remove the secondary cats and maybe that is why you say catless but you still have cats in your headers. if that is your case than those O2 sensors above are not good for you.
you should still have front and rear O2 sensors, they are just closer to the engine than mine. Hope this clear things up for you, AM changed the exhaust around 2010.5 +

hm i suppose that's possible, it certainly appears that way on the velocityap pipes, i guess i would just wonder why.
