Car Running Rough

I came out after work and started the car up and it is running really rough. The engine is shaking visibly. There is no check engine light.

Are these the main possibilities?

Bad Plug
Bad Plug wire
Bad coil

Checked the plug wires? Did the MAF come unplugged? Suck up any water through the intake?

Didnt you just have headers installed? Check your plug wires and see if any are contacting the headers and that all the boots are on tight.

We had a CTS V not to long along ago at the shop misfire like crazy and no SES light and it was a loose ground on the back of the head.

Yup...2 of them are sitting on the headers...one of them the rubber is split. I just ordered some Magnecore wires; and have some protective heat sleeves coming.
