Any chance its a bad fuel regulator? If it was dumping fuel back to the tank would result in low fuel pressure... just a thought.
clean the injectors or at least spray test them.
From a manual on EFI:
A vehicle that hesitates while accelerating or while driving up a hill may have a weak fuel pump. ... Dirty fuel injectors may cause the engine to run lean which will in turn, cause hesitation when accelerating.

I would not buy a tank until you know anything about the injectors, you may be paying $1000 to find out you still need injectors, check the injectors man!!
I recently had a plug start acting up. Random misfire and popping out the exhaust. The issue would come and go. Cold motor was when it was most noticeable.
Tracked the cylinder down via thermal gun. Thought it was everything BUT the plug you know cause it couldn't be that. Well it was a plug. Never have seen anything like that before.
Just a thought....
One other thing....you running a cat? Plugged or failing cats can cause all kinds of issues under load.....

I quickly re-read your initial post and I don't see anything mentioned about timing, specifically initial timing. Any idea what it is?

Timing is edis driven and as far as I know it’s plug and play. Cam sync was stabbed with the otc tool on tdc compression stroke. I don’t think there’s anywhere else to go from there.
Just going to throw this out. Try switching wires from left to right on o2 sensers. I had mine reversed. Idled great. Ran like crap like at 2500 rpm. Loaded up and popped a lot. I just replaced my in tank fuel pump and it runs at 90 psi at rail.
Good luck.
are your plug wires new? when i was putting my new ones on, i REALLY had to be sure they clicked on. i noticed on the third or fourth plug that something didnt fell quite right and half the ones i had already done took more force to feel the engagement.

I had forgotten about that Hick-up you had... No Cost to try that one...
Still chasing this, but work has me busy most days. Thanks again for helping me out!
