    I have a 2011 prius in the 220k range that feels is shaking under light acceleration. Acceleration in the electric zone does have an issue and if you get up about 3000 rpm it goes away. I have no codes. I cleaned the egr cooler and intake and it didn't seem to have a large affect. Any thoughts?

    I have owned the car for 3 years and there was some carbon build up, but there was still flow getting through.
