Rough running water getting somewhere its not supposed to....

I have a 2002 GT 5 speed, just got it not long ago. The first time I washed it I thought I might have gotten water in my cat backs. I started it up and started driving, ran like crap. I could feel it shaking, like it was missing a cylinder. Ran crappy through every gear up untill about 3,500 or so rpms and it would smooth out. I could tell a dramatic loss in power utill it smoothed out... So I ran it for about 1 1/2 hours and it went away. Washed it today and totally avoided the exhaust all together. And Im thinking maybe water is getting something wet under the hood from the hood scoop??? Im thinking it would be a smart idea to change the plugs???

Pull your COP's.
See if any of your plug wells are filled up with water.

Word.
If you find any moisture in the plug wells, also remove the rubber boots from the COP's and make sure the wires are dry.

And if there is water replace just the one or all? And im sure it would be safe to do that instead of just the rubber boot?

If there is water, you must remove the water. The presence of water is bad. It'll short out the spark coming from the coil to the spark plug, causing a misfire.

The COP should be fine if you dry it out. You need not replace the COP just because there's water under it.
