just got a new flappy actuator from roger. did not seem to be leaking or have any issue, but roger convinced me
to swap it out while intake is off. thanks roger!

as mentioned, the old one seemed to work fine, but the new one is much more responsive and fast in both directions.
the old one is slower and a bit sluggish

will I notice anything with the flappy being more responsive, or just greater peace of mind?

The Forgotten On

Mostly greater peace of mind knowing you won't have a vacuum leak. The engine doesn't respond that quickly anyway so the difference will be marginal but possibly noticeable.

How were you testing it? If you had the intake off and laying upside down such that the "axle" was contacting the bench or whatever it was laying on it will be sluggish to open (requiring several pulls on the vac) and slow in both directions. Mine did the same thing while I had it laying on a rubber mat. After a tip from another lister I turned the intake on it's side and it responded quickly and moved freely. The original was working fine, but with new axle bearings it was even more responsive. The seals in the original bearings crumbled when I tried to hook them and pluck them out - which increased my appreciation for air leak problems due to old seals.

with the actuators off the intake using a mityvac. doesn't sound as if I am going to experience any
big difference, but it was a good idea to replace. at the very least, since the new one behaves differently,
the old one, at 28 years old, was probably well into the back nine.

Agree...this is one of the best examples of a part to replace while the intake is off just due to age, regardless of how well it works. It's one of the more difficult things to replace.
