Honestly, I can't say that a tune up would fix the problem. However, there are many things that could cause this. For example, a sticking idle air control valve, EGR valve, temp sensor, throttle position sensor, vacuum leak. Just for the heck of it, remove one of the plugs and check its condition. That way we can eliminate that as a potential problem.
