  1. Powerloss... HELP!

    E39 M5 and E52 Z8 Discussion
    Hey guys. I've been having some bad powerless in the low rpm range up until around 4000 rpm and the SES light is on. I thought it was the MAF sensors so I changed both..still no difference. When I went to get the car registered, there was 4 codes that showed up. P0012, P0128, P0171, and P0345...
