Guys, I have 2012 LR4 5.0 that I just got two fresh codes on. According to my OBDII reader, these are the codes. I have seen this on the LR3's but I have not found any information on this on the 5.0's. The car is runs fine with no misses in the engine or rough idle. I have read where O2 sensor could be faulty or the MAF sensor is dirty? Any advice on where to start? Thanks!
