Had my Espar rebuilt but still giving me issues and will only run maybe 10% of the time, codes f52 and 54 which suggest fuel/intake/exhaust issues, place that rebuilt it assured me it was bench tested and working fine. I've checked intake and exhaust and can't see anything wrong. I am not sure how it's plumbed into fuel tank but seeing as it's factory figured there had to be a schematic for how it's routed? It's a 2008 EC210CL.
