i have a 2.2 4cylinder engine, ran a engine scan on engine,the code can up with

I did a compression check on the engine, number 2 cylinder came up with a low compression !! it was 120 !!! the other cylinder came up about 180

DO YOU FEEL A MISFIRE WHEN DRIVING THE CAR? OR JUST GETTING A MISFIRE CODE? YOU SAID THAT THE PLUG WAS CLEAN, WAS IT WET AS WELL WHEN COMPAIRED TO OTHER 3? WHAT WERE THE OTHER CYLS. COMPRESSION? HOW DOES EXHAUST LOOK,SMELL AND SOUND?

i pulled all of the plugs out and put new plugs and wires in, and started the car up, ran it for a little bit, and it had a rough idle to it. So I pulled all the plugs out and checked them out, number 2 spark plug was dry and had no smell of fuel. exhaust seems normal. what can i do next !!
