So the 30psi on the fuel rail is stable - meaning the same reading when it is hot, cold, running well, running like crap?

The vacuum solenoid valves are working - under what conditions were they tested? Back in the day I had a 280Z that acted similarly. A temperature sensor was faulty but bench tested OK - meaning it had the right resistance cold and hot - but it did not remain correct under prolonged heat. The end result was that the engine was enriching the mixture until it thought it warmed up - which it never did. It was eventually found after sitting on a diagnostics machine for about an hour.
