Technically you are correct. The bosch system is continuous with a 
fuel injecter for each cylinder. More accuratly when that cylinder 
fires if the injecter has put a different amount of fuel out for 
it(either too much, not enough or a crummy spray pattern) then it 
would give a different specific impulse. For that matter anything
that 
would cause an imbalance would do that including a stuck or sticking 
valve, a misajusted valve, carbon build-up, a problem in the ignition 
to that cylinder, etc. A good baseline test would probably be to do a 
compression test and make sure all cylinders are within 5% of each 
other and if they are then to test the fuel injectors and also the 
metering unit for balance.
