Trouble code p0171 and 0174 + 0116 or 0101
Hi all,
I need a help with my RR Sport 5.0 supercharged, 2011 year. The both codes appeard (0171 and 0174) and sometimes + 0116 (sometime this code alone) or with 0101. We found some small vacuum leak and repair it, but same problem. Both MAF changed, PCV changed, but still same problem. I guess it could be weak fuel pump or O2 sensors. Thank u for any help and advice.
