Toyota Repair: 88 Camry Idle, air intake hose, auto parts stores

Question
I have replaced the engine/ brake line and lights on my 88 Camry and tuned it up with in the last 1.5 years. The only thing I cant figure out is why it idles so high. After a warm up it'll go down and after driving @60mph it sticks. Any clue of what I can do to get it right?

Answer
Try removing the air intake hose at the throttle body and clean the inside of the throttle body with some air intake cleaner, available in a spray can at auto parts stores, use an old toothbrush to scrub the inside, open the throttle plate all the way and clean out the bore and the throttle plate, I think this will help.
