i had a simalar symtom with mine a couple of years ago, mine turned out to be a a cracked/broken away vacuum nipple underneath the inlet manifold (not seen) causing the fuel pressure not to rise in the fuel rail under accelaration.
(this vac pipe goes from underneath the inlet manifold to the fuel pressure regulator)
