Just did it a month ago as an experiment.
After i did it the idle was 1.5k w/o a/c. 1.0 w a/c
The problem is after a 20 minute drive u stop the car and do your thing... only to come back say 10 minutes later to start the car... idle w a/c drops to around 500... very hard to drive in the hot sun in city area.
So last week i 'Pluged the Cow' by disconnecting the vacuum hoses from the throttle body completely (1 in, 2 out) and and pluged the nipples with stoppers.
the 2 vacuum hoses are now directly linked to the power steering.
Driving is very much more comfortable now and oomph.
Idle is about the same with no fluctuation
