5 speed 300E Idles at 1500rpm

My car has begun idling at 1500 rpm even when fully warmed up. The engine temperature is normal and the car is running fine. Sometimes, the idle speed will drop to 900 or so by itself, but it will often remain at 1500. This isn't a huge problem in drivability except that it causes the engine speed to remain high during shifting. This is a major problem when I am in a big hurry. I even blew a shift into second once when I was showing off a bit.
So, I'm going to get working on the throttle linkage, but I wondered if there was an obvious place to start first.
