Fuel Filter. Even though pressure was within spec during idle - measured at fuel rail. Upon acceleration, insufficient "flow" getting to the rail & thus injectors. I even picked up a few codes (I seem to remember...maybe wrong about this though) that led me astray in my diagnosing process.
Anyway, same sypmtoms you're describing. I replaced the fuel filter...and it was like a new car. Interestingly, the filter wasn't old - a baffle/plate inside had dislodged partially blocking the outlet path.
You may have a fuel line restriction. Not necessarily at the filter.
Can you check fuel pressure at the rail - both at idle and then upon acceleration?

They checked fuel line pressure (they even checked the fuel, went into the tank and check for sediment, etc.).
I'm not sure where they checked. Where is 'the rail'? At the injector rail?
Where is the fuel filter on this? Is it easy, hard? I'm not a big DIY guy on this car (though I did change out the ETA myself, main wire harness too...). Not as easy to find things for me as the '85 FJ60 Landcruiser I have...
