at the risk of channelling tw, you need know what's broke before you try to fix it by throwing parts at it. if you're getting multi cyl misfire, and you only have two cyls testing bad... how do you know that's the whole multi group? right, you don't. it is *definitely* OK to solve a problem like this in an iterative fashion, fix what you can see wrong in front of you, test again, fix what shows up next. That's a perfectly fine strategy.

I don't know--do you--what the possible repair/replace solution options are for a fuel injector that tests this way? What about cleaning it? Like I said, *I* don't know in this case. As for misfires, there are a hundred and one ways for a cylinder to misfire. fuel/air/fire.. it is a mystical trinity.

What to do, is still a good question. I'd focus on what it would take to get the electrical readings of those injectors you can reach back into the good range. replace or repair and then go from there.
