I know it's not the same vendor -- Wait, it is the SAME vendor -- so how
is it that on ebay there is one Denso ignition pack for a 2005 3.3L

Your links shows $32 each.

The first one does, but it was $70 yesterday! (It shows as marked down
from that 70 and if you were unlucky enough to buy it yesterday, that's
what they charged! Do you think any webpage is smart enough to charge
more the first time you look at it and then lower the price a day later?
That's what a live salesman might do, and you could write software to do
it, I guess just using cookies would be enough, but I've never noticed a
substantial reduction in price before after only a day or two.)

The second one shows that price too, and it was that same price
yesterday.

Denso is a quality brand at a good price point.
[I go Denso although I have found generic Chinese equally useful.]
If you are replacing a COP in the rear bank which requires removal of
the intake manifold, replace all 3.

Makes sense.

Without a garage and another car and more energy than I have these days,
I don't think I can remove the intake manifold and also get it back on.
(I'm pretty sure I can do the first part.)

I have (or had**) a misfire on cylinder 1 and 2 out of 6, plus a random
misfire, but iiuc it could be the injector, the injector circuit, or a
couple less likely things (compression, fuel pressure).

**I just discovered this yesterday. I cleared those codes this morning
but haven't gone anywhere since. They're just about sure to re-apperar,
I assume. It runs smoothly, as nice as ever. Has plenty of
acceleration and power.


**I watched this video https://www.youtube.com/watch?v=fkQgNyUmDHo where
he replaces the spark plugs in the rear bank, in a car just like mine
but one year older. It takes 21 minutes not counting parts he skips
(including replacing the plugs!) and not counting reassembly, It's all
disassembly. Well,maybe I could do this. I suppose I could take
picture and make notes and then I could get it back together. I could
bring all the parts inside overnight.

(I'd like to do something fairly big at least once. I'd like to rebuild
an engine but I'll never do that.)
