Yes, there were definately no carbs on 85s and up, I have a funny feeling since 84 was a mid-year intro that EFI was available on them as well. Someone once told me no carbs at all on the 84s....but I never really believed that.
I've never seen a carbed 4Runner from 1985 on, and I've never seen anything but carbs on 1984s. That's just me, but I tend to go off of what I've seen. The 1984 FSM does show the EFI stuff, that's how I swapped the 84 Celica GT 22re into our 84. (The original 22r had a cracked block and I bought the whole car for $300.) I think 84 runners are pretty scarce anyway, and ones that came with EFI are probably a small percentage of those.
