Was just wondering if this is normal when I start up the car to get it warmed up, I feel a little vibration from my seat. Slowly goes away when the car is warmed up.

Solara350

My IS350 same thing, I also have RPM needle bouncing a little , sanuke told me to clean throttle body but it's still there I even unplugged battery and it's still there, my boss called Lexus Downtown in Toronto and asked , master tech told him it's normal even rpm slightly dipping , I went in the dealership and checked other IS350 RC350 they were acting the same, watch YouTube RCF damn same thing, my boss BMW X5 2017 he just leased for his wife , rpm acts the same and shaking. I am stumped on this I don't know if it's normal and all my previous cars don't have this , my 17 years old Toyota no shame no rpm dipping.
