It's been raining a lot and snowing so the other day I was backed to the house so the truck was facing a slight downhill , I popped the hood looking for a good place to run my amp wire and I noticed water was dripping from the cowl down on my intake and pooling up it was between the last 2 cylinders I didn't think much of it until I just pulled the coil and had filled the plug hole, so I used some skinny shop towels to dry it and put the old coil back in and started it up it sounds better, this weekend I will try to fix the cowl leak.... thanks gt and ses for the info thanks alot
