engine running a lil rough

i posted this a couple days ago but i dont think it got posted ....I recently overheated my xj and now its runnig a lil rough. I changed my plugs they looked fried and its a lil better but still rough. Almost sounds like when you have a little bit of moisture in the distributor cap. Just wonderig what might be wrong

Are you absolutely sure you got the plug wires back on the right plugs?

Have you tried a compression or leak down test on your cylinders/valves? Maybe you have low compression in one of your cylinders due to faulty rings or a burnt valve from the over heating.
