Does it run rough down the road. Could be intake gasket leaks, dirty throttle plates, if a misfire could be tune up.

More then likely vacuum leaking, spray water with a spray bottle around intake gaskets. Spray good amounts to see if the idle changes for a leak. Clean throttle with some good carb cleaner and remove all black soot inside.
