Dumb question - If the shop diagnosed the problem, why didn't they just fix it?

Vacuum leaks are easy fixes. But to tell the truth, if you're not familiar enough with working on cars to know what a vacuum leak is or how to diagnose it, then you are only going to get yourself in trouble taking things apart.

I'm not trying to insult you, just politely suggesting that you might get in over your head real fast..... And then you'll have to pay somebody to undo your mistakes, and that will get expensive real fast.

If you're determined to plunge in anyway, what you are looking for is any hose or fitting attached to the intake manifold that is leaking air in. There are a few ways to do this. First and most obvious is listen for the hissing of air leaking in. The second is by spraying carb cleaner on the suspected area, and watching for a surge in engine speed indicating that carb cleaner is getting sucked in through the leak.

Good luck.....

My advice is to let your shop fix what they diagnosed.
