not really sure if its a problem ive never seen it before i have a 1989 mustang lx 5.0 . today i had the hood up and touched the coil wire and it started arcing on my hand but it wasnt shocking me i thought a bad spot on the wire but you can run your hand up and down the wire and it does it every wear on the coil wire my car runs fine besides the idle going up and down sometimes just wonderin if any one else has seen this before. and its got msd wires if thats makes a difference

And that unstable idle could also be your IAC going south. You can take it off and clean it, but its a pain in the arse. Last time I just bought a new one. :bigthumbsup
