Just wondering, I have a K&N Air Filter in my car and I took off the Silencer. Now I have a really rough idle. kinda cool though It feels like I have a cam and Idles like it. Any Suggestions

Doing those things should not make the car idle any differently. I'd check the vacuum lines for breaks/splits, or maybe a disconnected line.

Bob is right, you know it is quite easy to knock off the vacuum lines.
