Need help! LS1 sparking at valve covers My z28 that I use for a daily has started running rough in the past day or 2. I opened the hood tonight to check if any of the plug wires were loose or cut in 2, and noticed almost every coil pack/ area on the passenger side was arcing to the valve cover. It comes and goes as if there is a bad ground also. Any of you all know where to start looking for possible issues, bad coil, ground to valve cover or engine? Any help is appreciated.
