OK. You pull the vacuum line off the brake booster and plug the line?
OR....You pull the vacuum line off the brake booster and let the vacuum line suck air?
Which did you do?
If you pull off the line and plug it and the idle does not change, that would imply no leaks in the booster.
And did you plug the line to the purge valve when you pulled it?
And did the idle improve, smooth out, when it got higher?
