Yes. Check the plastic vacuum line that I referenced in my earlier reply. That is the most common place for a vacuum leak.
I had a similar problem, but the idle went up and down like crazy. The car was not driveable. The vacuum leak was at the intake manifold gasket, but I believe my situation was very unusual.
You can test a mass air meter if you have a scope, but I've never done it.
I gather from the techs that it takes more time to test them than they're worth.
Instead, most shops keep a good mass air meter on hand and switch it out to see if it makes a difference.
You can replace your mass air meter with a phillips head screwdriver and about 15-20 minutes. The problem is that you don't have a known good spare MAM to swap with yours, and they cost a couple hundred dollars. Most shops don't allow return on electrical items, so tread cautiously on this.
The throttle actuator costs about $1,200 by the way, so keep your fingers crossed.
