OK, I got the new spark plugs in. The ones in cylinder 1, 3, 4, and 6 looked okay- whitish brownish patina. The plugs from 5 and 2 looked black and presumably fouled. 5 and 2 are both controlled by the same coil, so there we go.

However- I have not put the plenum back on yet because I am not confident in my spark plug wires. I've tried measuring resistance but I can't get a decent reading- one I can't get a reading at all, one I will get a reading for a split second on the 200k setting, and one reads around 17-18k. That doesn't sounds right to me at all. Aren't spark plug wires just really, really well insulated wires? Why can't I get a decent reading? Is there a special test I could do? I don't object to replacing them, but I'm not sure my local parts store will have them and I really don't want to wait for more parts. Besides- I know at least two of them were working before. Your input is appreciated.

Thanks!
