Where is the idle control valve located in 2004 buick rendezvous? Also if this has gone out, is it safe for me to drive on the highway?

It is on the throttle body. You need to post only once. We all look at the questions and answers.

By the way. I suggest getting it fixed asap as a high idle can cause stopping issues

If you cover the throttle body opening and it idles down and dies you know the problem is within the throttle body area or computer control wires etc. If it doesnt you have a big vacuum leak.

I will check for the vacuum leak first. That seems like it would be easier to fix.

When I got home I took a look under the hood and listened for a whistling sound. Turns out that when I got my oil changed last week the kid that took my air filter out never connected it back up. The air filter wasn't put in right and the hose was never connected. Once I put it all back together my car has been driving perfectly fine. Never going back to that place again.
