Need help, corrosion on coil packs and spark plug wires Hey guys, so I changed my spark plugs this past weekend and noticed I had green corrosion on two of my coil packs and two spark plug wires. I did my best to clean everything off then put everything back together but I noticed my car isn't running as good as before. Does this mean I need to replace my coil packs that had the green corrosion on it along with the spark plug wires? or is there a away around replacing everything with new parts like maybe getting a better cleaning agent and recleaning it? So I guess what I'm really asking is can corrosion destroy the coil packs and spark plug wires?'

You can test individual spark plug wires with a multimeter - they should show between 397-1484 ohms of resistance - replace any wire with higher resistance. I would not replace ignition coils unless you are getting misfires. You can safely clean off corrosion with WD-40.
