I had to make a kinda long trip in my car the other day, (2 hrs) and it ran fine and everything but when I got off the interstate it would idle at 1500 rpm instead of the usual 750-800. I thought it would stop but it hasnt. It still runs good, but it just idles high and its annoying. Any thoughts?

loose throttle cable ?

Thanks again!
