5VZ-FE throttle bodies

So I have high idle problems with my 1996 V6.
There is a bit of side play in the butterfly shaft and the dashpot/stop linkage seems to resist the final few mm of closure as well.
I just bought a throttle body from a 2001 wreck and it does not have the dashpot and extra linkage.
The question I have is whether the missing dashpot will cause a harsher butterfly closing and result in a revs undershoot and severe leanup?
Not sure if the later 2001 ecu somehow adjusts for this snap closure.

Cheers.

OK so the butterfly shaft had a few mm of up/down play when held open which is the air leak causing high idle.
I swapped for the 2001 body which works great.
The later body has all the linkages on the butterfly shaft instead of using an auxillary shaft. Consequently I had to make a new throttle cable bracket to move the cable closer to the butterfly shaft.
The cruise control cable is also now too long so I will make a new bracket for that later.
Just a heads up for 1996 owners.

Attached is a fabricated throttle cable bracket for 1996 models to use later throttle bodies.
