I would like to know what happen to user named Martin he posted a question back in october 2015 now I have a same problem with my International Maxxforce. my check engine light is on and there is a one active code it is SPN 524285 FMI 14...Does anyone know what's causing this problem. I drove from IL down to San Antonio with 14,000lbs and this truck has been doing 68 MPH and than in a sec on little or now hill down to 55 MPH and than just kind of stay for miles on 55 MPH..I know this maxxforce is junk but this truck has been ok for almost 3 years and unfortunately I do have to deal with it for another year. I did replace EBPV valve last year in May. Any help is really appreciated.
