My cayenne misfire, engine fire does not stand, plugs are wet. My electrician changed plugs, engine control unit but still problem persist. When he removed plugs and injectors to passenger cylinder it works perfectly but when he brought passengers sides own to driver side, problem persist
Do you

The injector driver or the coil driver/ignitor may be bad on that side. I am attaching a link to a walk through diagnostic explaining the most common problems causing mis-fires. Just use the link below;
