Coil rail fires which plug?

[TJ Jim]

Put new plugs in today since I have no idea when they were last replaced. They actually looked pretty good. #2 and #6 had a pretty big gap .65 or so and #2 was missing a bit of electrode? The rest were real close to .35. So my question is there are three coils so which cylinders do they fire?

Waste spark system...so when it's firing a cylinder with the intake valve open and injector squirting it's also firing on a dead cylinder.

So is the coil closest to the firewall firing #5 & #6 or different plugs?

The pairs are 1 and 6, 2 and 5, 3 and 4.

I don't remember which coil goes to which pairing.

It should be in the FSM which can be found under resources.

That’s what I was looking for. Since my #2 plug and #6 plug wore different from the other four plugs I thought maybe they were on the same coil. I’ll just assume the gap was set incorrectly when installed.
