Here we go again

Well, it has been 5 years since I sold my 99. Now my youngest has a 2000. Happy to say he already has a riffraff sticker
so here are the issues,
when he bought it, we knew it needed injectors. Now the weather is getting colder, the injectors are indeed and issue
my oldest went out and bought used for injectors for my youngest
Everything is installed
so, we now have a major fuel issue, I have white/black cloud non stop,
I have a slow start, which makes me think automatically bad injector, used a thermo camera, identified either 3 or 4 not firing. Sure as hell, wire was cut on three, repaired, but still dumping fuel.
buzz test comes back fine, contribution comes back fine
anyone else think I have over sized injectors??
tomorrow I will be going back to the original injectors. I will then buzz test and then contributing

Aw that sucks. Easy to suspect the used injectors. Got some miles on the swapped in set, to clear out air/oil/fuel from unintended places?

Surprised the contribution is ok, given the smoking issues.

Any codes?

Are you sure the injectors are fully seated? copper washers and o-rings good/ replaced.
If they were bigger injectors without proper tunes, it would have a weird idle and be super touchy

lol, I was wrapped up in the smoke, I didn’t even run codes, I came with the mindset, it wasn’t broke until I touched it.
Ran it on a 6 mile run to clear out all of the excess.

I need to look at the injectors again for this, I had thought, still think, if it were o rings, would I not see.. oil in coolant, oil in tail pipe, or oil in fuel bowl?
mid it were the cups, should I not see oil in the coolant??

please know, these at nothing more then questions?

So looking at the injector, the bottom o ring would be suspect, but that would require the copper washer to be an issue as well?

My oldest, who bought the used set of injectors for my youngest, called the guy who he bought the injectors from, they were not stock injectors. They are stage 2.
At least these are not difficult to do. But damnit. Lol

If you are getting oil in fuel and coolant, that's a different issue. That would be injector o-rings and possibly a bad oil cooler, no?

well, at least you got the info on the injectors. would have been nice to know ahead of time though.

Fix it cheap and find out. Yes I did that, too.
Just get the old ones rebuilt, or buy some new ones if you can find them.
Move on to the next big thing in life.

Gonna need tunes to run those injectors properly. "Stage 2" is a pretty generic description but some conservative ballpark tunes will be 1000 times better than OEM.
