What are these plugs for?

I understand your skepticism. 😀

There's a bit more to the story. When I got the car, the intake manifold was broken and the bolts weren't very tight. Carbon soot was building up in the crankcase from exhaust blowing there. The oil drained out full of it. The joke was, it passed smog because so little was going out the tailpipe. Even stranger, there was no coolant in the oil, and no oil or gasses in the coolant. Once the intake was replaced and sealed up nice, the carbon soot was gone, but now it refused to go down to curb idle, despite all efforts at adjustment. Then just as suddenly, it did fine once a new cat was swapped in. Nothing else changed. I did the adjustments myself, and checked everything after the swap. And no, the motor wasn't ruined, everything checks out fine and it runs like new with a little over 100k.

So I'm all ears for alternative explanations. Or universes. 😕😱

I was going to junk it, but decided if it can survive that it's either charmed or built like a tank.

emissions, it warms the oxygen sensor up faster for better control of the air fuel mixture and warms up the cat converter for better emissions out of the tail pipe.

Each plug has a wire that is hot. What should I do with them. Can I just wrap them in electrical tape and stash them?
