The decelerate sharply is using the engine, not the brakes. You have to create the vacuum of deceleration in the cylinders. That indicates valve stems and seals are worn. If you have light blue-grey smoke on Acceleration, that usually implicates rings... much worse.

Again, I consider the worn seal problem mostly innocuous. Might warrant a compression check for your peace of mind, and plugs may need more attention.
