Re: arcing near plugs

sounds like you need some new plug wires, these are heat shields, I would leave it and replace your plug wires. Make sure the shield is not chafing on the plug boot.

Re: arcing near plugs

the ignition power is going to take the least resistance path to ground. check you plug condition and that the wire is on ok. If that looks good sounds like some cheap set of wires.
