Q: Fix vacuum leak and reset idle.
I did a tuneup, but I think I have a vacuum leak. All I need is for the idle to be reset and a diagnosis of what else needs to be done.
The idle should not be adjusted unless it has been tampered with. The idle is controlled by the idle air control valve. The vacuum leak once identified and fixed should correct any idle problems you have.

These make noise that is proportional with engine...
