I've heard the gasket and o-rings on the oil filler cap can cause problems, try those next.

As for finding problems with FI systems allways check the ignition first. Change the plugs, check the resistence of the wires, check the coil, etc. As for a guess, look at the cylinder head temp sensor. It is one of the few things that changes with temp and can drastically affect how the engine runs.

Look at the Porsche 914 fans web site in the tech section there is a L-Jet vac hose diagram. If you replaced the hoses one by one you should not have switched anything, but maybe they were mixed up to begin with.
