LR3 V6 CEL help

Been looking all over the internet and could use some help.

I have a 06 LR3 with a v6. It has 141k on it. I purchased it and after driving it for 3 days and 200 miles the CEL came on.

I ran the code and P0172, and P0175 came on.

So I checked vacuum leaks with carb cleaner and nothing. Replaced the MAF...still on. Finally just replaced all 4 o2 sensors with Bousch sensors and the CEL came back on after about 12 miles. But now we have 2 more.

P0172-same as original
P0175-same as original

So how is it that I can have rich and lean at the same time??

Im hoping that I don't need new cats as they are not cheap. Any help and direction would be great.

You did put them in the correct places as they are different. If so, take them out and put the old ones back in and see if the codes change - need to clear codes first. Is this petrol or diesel V6
