I am guessing you mean the Idle Air Control (IAC). If the answer is yes (it would be the silver thing on the forward portion of the plenum and have a hose that goes to the air intake tube). I have seen IACs quit, grind, smoke.....and on and on. It is a common piece that goes out. I think I have replaced mine twice (in almost 100k miles) and had to clean it quite a few times. It just get gunked up, and a good spraying of brake or carb cleaner usually works really well.
Good luck with fixing it! It should be easy and done in 10 minutes or less.
