I assume that you replaced the seals around the holders as well as the seals around the injectors when you replaced them - then there's the long molded rubber air hose in the middle of the manifold assembly - mine was hard as a rock, and hadn't made a seal for years. Only way to get at it is to dis-assemble the manifold. There are LOTS of hoses that can leak. Every bolt on one side of my intake manifold to head joint was loose - as in I removed them with my fingers. There are also the 8 tubes between the manifold and the plenum beneath it that can leak. The symptoms were started with a rough idle, moved to hard to start, and ended with refusing to start. After I took it apart, I was amazed that it ever ran --- the PO was an independent "Mercedes Shop" in Ft. Worth - I think they pieced this car together from many donors, too late at night, after too many beers.

I have looked for intake leaks, I have also replaced injectors, adjusted mixture, new plugs, wires, cap, rotor, etc. Tried known good idle air control valve and computer. I did find a bad throttle switch and replaced that.
