First off, I would like to express my sincere thanks to all who have responded in the past to my posts seeking advice. I very much appreciate your efforts to help. I tried searching the internet for this condition but could not quite get the search wording right. In this case I am driving a 2005 Ford Escape V6, and when I am cruising at, say, 40mph, and I lift my foot from the gas pedal due to traffic conditions, when I depress the gas pedal again I get a thunk. If I depress it VERY slowly, no thunk, Also, no thunk when accelerating from a stop. Sometimes, but not always, I get a thunk when the transmission upshifts.
As I am writing this, CarTalk suggests this post, which is very close to what I am experiencing: Feeling a “bump” in the gas pedal after coasting…?
I changed the right front hydraulic motor mount right after I got this car about two months ago. Have only been driving it regular for about three weeks. Besides motor and transmission mounts, might there be anything else that could be causing this condition? Again, no thunk when taking off from a stop. This happens at faster and slower speeds than 40mph.
