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.
