Default Engine Accelerates at Start and remains there

2001 SL2 5 Speed w/140k miles

When I go to start my car the engine races to 3500 and decreases to 3k and remains there. How can I stop my engine from racing and get it so it idles and drives normally. It usually idles at 800rpm. I took the car out on the freeway to see if it would fix itself. But, it did not help. The carburetor looked clean. Waterpump replaced in June 2013 by shop.

Welcome to the Board.

Check for vacuum leaks. 3000RPM sounds about the right RPM for the brake booster vacuum hose to be off/leaking or the PCV vacuum hose to be off/leaking.
If those are ok possible jammed throttle cable.
