plug wires jumping spark

i fired my car up today and heard a slight ticking sound coming from the passenger side of my motor. when i looked closer i noticed a spark jumping from the plug boot to the plug/block. What causes this and how do i fix it. the wires are only one season old and are not cracked or bad. any suggestions help.

have you checked the spark plug. Sometimes when the gap is too wide, or the plug is fouled, etc. the spark will take the route of least resistance.

That is actually the first thing I thought of when I saw it. Thanks for the reply I'm going to look into it more this afternoon. If anyone thinks of anything else please let me know. I'll let you know how I make out tonight. Thanks again

I had this happen years ago with a set of new repop HiPo plug wires. Don't remember where I got them but they were not the ones Marti makes. I replaced the boots with those from a Motorcraft wire set I had laying around and that solved the problem.

Yes, I also had a set of older non Marti repro wires split a boot. Only missed under load and drove me crazy for a little while. The split was not visible until I removed the boot.

well after spending a little more time with this problem, changing wires and regapping the plug. i finally pulled the plug and looked at it more and the white part had small cracks in it. So I replaced the plug and the problem went away. thanks for all the responses with this matter.
