Fuel ijector adjustment
 

I own a 1987 300sdl. Recently i noticed two (2) fittings leaking at the top of the fuel injection pump and decided to repair them. I removed the fitting at the pump and removed the fitting using a special socket. When i reinstalled the fitting with new o ring and copper gasket, my car idled poorly. Additionaly, i'm not sure of the torque on the fitting. I need help!
