If Cam Synchronizer fails,then it has to be replaced.
While replacing,
Just mark the old one an put the new one in in the same spot. In this procedure no need to use the alignment tool, and put the engine on tdc. After installing start the engine and check,does it starts right up and seems to run good.
In most cases these method works just fine as long as you didnt move the engine. In most cases if the synchronizer was installed wrong you would have a check engine light and the engine would not run correctely. If you have no running issues your are likely fine. The idle speed should not have been effected and if it was the idle would likely roll up and down. I would start with making sure someone hasn't screwed the throttle hard stop in a bit and if so back it out a bit to be sure the throttle dosnt stick and it should be fine.

The idle is around 900rpm.If it seems just a bit high. Then it could the synchro not being in the exact spot cause this.
This details will help.
Thanks.
