For that matter, I have lots of good S4 injectors, I will bring a set down (but I am guessing that is not the problem, I think it is sensor related). We will check the timing too. (I know all coils are firing, we already tested that). If the engine didn't idle so smoothly, I would be guessing vacuum leak.

Fuel pressure is also a good one (I think I have a gauge somewhere).

It is also possible that I have driven my Haltech '86 so long that I forgot how slowly stock rotaries rev. (although I think the '91 revs faster).
