water dident make it crack it just cracked from wear.. mine had a light crack on the top, and one had it down the side. then when water got in them they started to fail witch caused the roughness and boging

just dried it with rags...im sure theres still moisture somewhere..im gonna go look for any more wet spots but i guess ill just have to wait a while and see if it changes when everything is completely dry? this is my DD is it o.k. to drive the car like this if i have to?
 
it's possible it filled the bore for the plug up with water. how much water did you use? i never run very much around that stuff just for this reason, set the hose to mist and let it sort of "run" water off while mopping it up with a towel or microfiber.
 
i did for about 10 miles before i decided i dident wanna risk it.. if ur getting a misfire i wouldent. but like i said i did the same thing u did and that was my problem. make sure there seated right now water on the connector or a crack in the boot that maybe water got into
 
if none of that works.. go get the cops tested make sure there all fireing.. then again.. if it ran fine before u washed it.. its prob not the plugs
 
Misfire. not burning everything so its def a COP or spark plug. if its none of that something could have been shorted out. but i highly doubt that.
 
make sure u dident pull a wire loose or anything while you were cleaning around that area
 
start it up make sure its still running rough.. then pop the hood and one at a time un plug the cop's if it gets worse thats a good one d oit untill u get to one that when u unplug it the idle dosent change and it dosent get worse. then thats ur problem.. but dont stop make sure there all still good.. doing this you MAY.. throw a code. but it dident in mine
