Default Idles pretty rough

For maybe two weeks now my car has been idling pretty rough, like my whole car is shaking pretty bad. It also sounds like there is a ticking sound coming from under the car. I recently had nitrous installed and I'm wondering if maybe its from that and my spark plugs are bad? Any ideas?

the first thing i would do is check all the coil harnesses. i didn't connect one of mine properly and it worked itself loose, the car shook like a ****. if that's not it change the plugs if you haven't done so already with a set thats a set that's maybe a step or two colder.

when was your last tune up anyway?
