Before changing anything I would test it. I know this has to do with your high idle so here is an old school test, I love old school, low tech testing, ask anyone on here.

With the engine running and the air cleaner off get a spray bottle, like an old Windex bottle. Fill it will plain water. Now spray around the bottom of the throttle body, where the gasket is. (you can also use starting fluid, but don’t).

Now pay attention to the idle speed, if there is a leak at the gasket the idle will change, rise or lower depending on the problem.

No change, no problem. If the idle changes then there is a problem. Get a gasket and change it. Just remember that a vacuum leak around the intake or a vacuum line can also cause an idle problem.

I have had vacuum leaks in fuel injection systems cause all sorts of problems, from idle surges to no start.

Once you are sure that you have vacuum leak, and where it is we will go about fixing it.

I just don’t like throwing parts at a problem, test, test, test.

Thank God you're still alive Jaime....That don't sound too safe or smart :) That's like looking for a gas or propane leak with a lit match lol
LOL

But it works.

You may not be around to fix the leak after you find it.

Thats why i didn't recomend the starting fluid test.
