You can check for vacuum leak(s) and test the EGR system. Possible poor quality fuel or injector problem. Low compression will also cause rough idle and smooth out with throttle! Let's see what else,.......OH YEAH, you could always have a mechanic look at it for you!
Scoping and scan testing should do the trick as far as finding the problem!

Do you have a check engine light on? If so, have codes scanned at an autozone for free and post results.
