Auto? Brake stand it and load it up good and see it it misses.
What's the running compression?

Swapped out the injectors for another set of green tops, no difference at all. The hesitation is still there. Ugh... this is getting annoying!
Could the neutral safety switch cause any problems? I'm just thinking, since my friend pointed out last week that my reverse lights didn't work. After checking the fuse and probing the reverse light bulbs, I believe the neutral safety switch has failed. IIRC, it provides a signal to the ECU to raise the idle in P and N.
Neutral safety switch prevents the starter from engaging if the position of the switch is not in either Park or Neutral. Afaik your idle will not be affected by a failed switch(had it happen on a 240 and it didn't affect idle).
This happened to me once when my spark plug cables failed internally. There was no visible sign they were bad, but replacing them fixed the problem. Did you already try swapping those out?After driving it, I noticed the hesitation/sluggishness is up until around 3000 RPM.

I hear there's supposed to be some type of heat shield between the exhaust manifold and the spark plugs, but those are long gone on my car.
When I had the problem, it was on a set that was only a few months old. I use Duralast wires. I'm not sure if FCP's have any difference in quality control. It's happened to me more than once, so I have to assume some wires are just duds.
Absolutely.
I understand that the cam gear is lined up, but are you certain about the crank gear too? And for reference, my kid's '93 940T with an Enem V15T (stock beyond that) draws 18-19 in/hg at idle, so you should very much be in that neighborhood. Also, I see you said your valves are adjusted, what clearance did you use?
