Hey people I need another opinion of a vehicle I am working on. It is a 2002 c240, I am getting a misfire on cylinder #6 that keeps returning and I am running out of ideas. So far I know that I have a good ignition coil and suppressors on the cylinder, it also has good spark plugs. The fuel pressure, fuel injectors and the fuel itself is known to be good. I have performed bore scopes on the cylinders and found no damage or carbon buildup. Cylinder leak down test got 2% leakdown with 169psi on compression. I also know that I have a good MAF. I also know that the problem is not mechanical as the valves and cam are fine. I have to be overlooking something so any help would be greatly appreciated. Thanks in advance.
