Hello all!!!! just joined.. I like this place already O0.. here is my issue... Uh oh.. My car started running really rough yesterday like one of the cylinders was not firing or so. So this morning when I got up I went out to check all the spark plug wire connections and found that the first two on the passenger side had coolant in them, almost to the point where you can't see the plug itself.. and my Check Engine light is blinking!!!! the car runs rough until it gets up to about highway speed then it seems to smooth out.. Could this be a cracked intake or cracked head gaskets? Should I try replacing the intake first or just go ahead and replace the engine.. It has 153,000 miles on it as of now.
