I hate to ask but I just need some clarification on something… I have a 2016 650i I installed DP and had to remove the one in the driver side cause it started leaking from the flex pipe seem like the weld got weak. Once I got the new DP installed I also installed the intake from ARM everything has working fine until I got my check engine light reading P170 bank 1 too lean. My question is could it be that the passenger side DP wasn’t installed correctly or could it be from the intake that I installed?
