S600 NA 1-3 cylinder misfire

Hi!
Right coilpack went bad and I ordered new one from ebay. Before was entire bank out, now cylinders 1-3. When I clear codes and start driving, for moment it has all power and then faults come back. Replaced sparkplugs, voltage transformer, injectors seemed in good condition, compression is decent, swapped o2 sensors, but nothing. Is that new(remanufactured) chinese coil bad?
