Never had this problem until I installed a spoolinup coil on plug. With my 280's it will idle below 700 sometimes and blow the fuse. Even on the short drives I will get shocked and I think its related. All of my ground straps are in place but factory ones. Should I invest in an aftermarket grounding kit?

 

rub a ballon on your head (assuming you have hair) for about 15 seconds and put it against the nearest wall. If it sticks to the wall, then you may or may not need a grounding kit.

 

If I was still 5 I would. I've already read of people using a larger fuse for coil on plugs but just installing a larger fuse isn't always the right answer. Things i've checked already: O2 wires for shorts, engine grounds, its not my seats when I slide on them.
