I have a 2012 Cl63 Amg 59k miles bought at auction with flood damage title and injectors on passenger side not actuating in Xentry test with a new ECU. New plugs wires and coils and 02 sensor. 4 Plugs on one side were fouled black as was o2sensir. I changed ECU Still no actuating of those injectors and slow acceleration. I cannot locate area of water or flood intrusion. Really at a loss. I'm getting misfire crankshaft errors p something. Any ideas? Someone removed the injector soundproofing or padding insulation and high pressure fuel pump insulation. The Sam's have been checked and I replaced the fuel pump relay in both front and rear sam just in case. Any help would be aporeciated. Maybe unrelated but the sound amp was missing
Thanks
