Q: Engine pulls/bucks at highway speeds

asked by on July 02, 2016

Last week my car started pulling on the highway around 60mph 2500ish rpms. I thought it was the vaccum advance and swapped it out. It was leaking so I thought the issue was found and solved but now it does the exact same thing around 50mph 2000ish rpm. I have better vaccum pressure now but i don't know what it could be.

My car has 56000 miles.
My car has an automatic transmission.
