There's a fine little conical fuel filter screen in each injector and any debris from orings breaking down or corrosion from the euro cast iron fuel head should stop there.

Carbon from gasoline eventually builds up on the injector pintle and seat and it can have a lousy spray pattern and or leak down into the intake ports after shutting the motor off because CIS injectors stay open all the time unlike electronic injectors that are constantly opening and closing so they stay clean.
Using the best gas and techron or seafoam helps to keep that stuff somewhat rinsed off.

Hard to say whats going on with yours without seeing them and sticking them in empty clean 12oz water bottles and pressing the sensor plate down while the pumps are running and watching the spray pattern and measuring the fuel quantity from each injector.

If you have 6 good lines and injectors coming in the mail you could try those.
