Okay, so what did I do wrong?

You plugged the spark plug wires into the little plastic wire holders, right? (You didn't rip them off and throw them away, did you?)

Those wire holders should space the wires apart enough to keep them from arcing...

New wires, and they arch, where are they arching. Are you sure the boots on the plugs are seated

Yes, I've kept those wire-holders. But the sparks are coming from one spark-plug wire near the dist-cap to some unrelated wire near it. Is it just a matter of getting this one, problem spark-plug wire away from that other, unrelated wire? (Thanks!)

Could be. (That "unrelated" wire wouldn't happen to be the one at the center of the distributor cap, would it?)

Try and separate them. With the engine off, please! (zZZZAP, Ouch!!)

I'll try tomorrow and report back. ty.

That is a cap-wire set, right, the wires at the cap don`t come off. Im sure these are aftermarket, You have a defect and need a new set.

Sounds to me like you have a defective spark-plug wire. This is probably not a set you got from a Toyota dealer, is it?

That "unrelated" wire is in its proper location, I assume.

If you can see sparking voltage arcing across to anything,..then the insulation of the spark-plug wire has failed. We are talking about a bright white to blue arc here? If yes, the leads are no good.

However, if you mean the arcing is occuring as viewed in near cpmplete or complete darkness as a ghostly looking arc,..that is not leakage, but corona which is relatively normal.

========================== As another poster suggested, get rid of those wires and buy new wires from the Toyota dealer (or online genuine parts) and install them exactly as the originals. It has often been reported that after market electrical components can cause problems. ========================== Hey, some of us are slow learners. I changed the water pump on my Toyota truck a number of years ago, with a water pump from Pep Boys. A while later the shaft fell out on the freeway and I had to pay to be towed apx. 50 miles home. Didn't feel like doing the work myself, so I had a trusted local radiator shop install a new NAPA water pump. Last Sunday, it failed and I paid $85 to be towed apx. 17 miles to home. This time --- I bought the Toyota water pump.

How long did the NAPA water pump last?

The Pep Boys water pump failed within... weeks? months?

Ive never seen a Corona discharge, I dought new factory wires do that.

Would you believe these were NAPA park-plug wires.

Okay, I've learned, I'll get the Toyota Dealer wires.

It's a phenomona which occurs near conductors of high voltage including the old tubes or valves in TVs radios, but especially transmitters where voltages and current are great. I;ve seen it in total dark around car ignitions wiring and sparkplug dust-covers as a ghostly blue hue. Its a little hard to see until,your eyes react to total dark, in which you are viewing the running engine.

Shop around on line; you can get big discounts. Then, call the dealer and order them; tell them =you saw the parts online. Champion Toyota in Texas will ship anywhere and has good prices. Jaffarian's in Haverhill, MA is also good, ask for On-line sales.

Hey! What's a few Volts between friends?

NAPA does have a reputation for carrying good quality in the aftermarket, but I just had one of their water pumps go out and replaced it this time with a genuine Toyota part.

you might look at this site

That's because Toyota doesn't make a Corona anymore. (yuk yuk)

My brother (ex brother now-- long story) has worked for NAPA for almost 20 years. He has never been able to give me a good part the first time. I almost always (when i used to buy from him, get two or sometimes three parts before I got one that was correct or would even work. Not only that, but he would tell me he was giving me a good price "because I was his brother" and usually I'd get screwed somehow.

I feel confident, though, buying RTV sealant and other consumables at NAPA, but I have certainly given up trying to buy parts there.
