Help car shaking on high speed - powertrain issue?

car shaking on high speed - powertrain issue?
My car shakes a little bit, back and force, on high speed like 60-75 miles. I feel it on my driver sit. I balance tires twice and it did not help. I went to Nissan dealer (I did not have Infiniti near by) and they said it might be powertrain and suggested to go to Infititi dealer. Also, I have check engine light (random misfire code) appearing every 3 months. I replaces spark plugs and but the light still appears randomly after drving 2K when I start a car, only when I start a car.
I wondering if anybody can suggest based on previous experience how I can differentiate between powertrain issue and random engine misfire. I am trying to figure out what causes car shaking a little bit on high speed,where to invest money
I have g37s 6MT 2009

I have the same problem at high speeds. I went to the dealer and they said my U-Joints are worn (did not tell them about the swaying so may not be the cause). Recommended that I replace the drivetrain. Didn't do it since they wanted to charge me 1.3k to do it but I did have a mechanic look at it and he said there is a little play in them but that it wasn't a crucial fix. Lemme know what you find out im curious

thank you for your replies.
I have original wheels. The code for engine check engine "Random misfire".
The vibration is small. It is pretty consistent but it happens only on high speed, like 65-70miles/hour. I do not drive on highway every day, so I do not experience it all the time. If it continues, I'll go to mechanic or dealer.
