Hi.I have a problem. When I smoth reving at idle,when rpm goes to the 1300 I start to feel vibration to the steering wheel and body till the rpm rich 1500rpm. Also,when i driving and make a load,for e.x feel the most when driving at 90kmh,and 7 gear engaged,then engine rpm is in thsi range,and when I start to acelerate,i start feel vibration on steering wheel and body. Also,I noticed,that when I reving at idle with open door,at this RPM range the exhaust start to change the sound,its maybe more louder..the feeling that he is resonating.. I have car for 2 years,and till me the DPF fitler has been removed(I think there is free space in the mufler..DPF taked out ant the muffler with free space in it fited back) Can free DPF muffler(tank) affect it,and exhasut system now at certain rpm starts to resonating and making vibration?Also I cheked all exhaust ruber mounts and heat shields,all is perfect. And yes...this is now the mounts problem,I have new instaled engine and transsmisiont mounts,and its OEM 
Sry for low english Please help Or maybe in the om642 its normal,and at this rpm the engine runs like a out off balance,and making a slight vibration?
