There are only a few replacement injectors, and they have a calibrated cubic centimeter per minute flow rate. Blue injectors are rated 477-483 cc/min at 33 psi, but there are three general ratings. First 5.0 CFi's were only 120 hp, 213 lb-ft engines, theGreen injector 3.8's even less. Ford rate them at lb/hr or grams per second, and have a standard test pressure. There isn't that many different ones, Ford kept the CFi 2-bbl engine ratings between 115 to 180 hp for 3.8, 4.2 and 5.0, and stepped the injectors up just by color.
A ford CFI unit from a 3.8-4.2-5.0-5.8 have Green 37, Blue 46, or Grey 52 lb/hour, low impedence (2 to 2-1/4 ohm) Bosch injectors under a Ford part number. Grey injectors are very high flow, they have no return line on early versions. The V8 ones ran at really low pressure, and were much bigger, about 483 cc/min from memory, when tested at about 39 psi or so.

They are still around, but not all of them. Ford changed the pressure limits, but the injectors are common enough. I have that Bosch info for CFI's, studied them in depth.
The HSC/HSO 2.3 and 2.5 didn't use the same injectors, there is no cross over. Ford US V6 and V8 CFi used the Bosch injector,
not the VQ30ENissan/ Chrysler/GM items the liitle TBi Tempo/Taurus 'four' has.
Best option is always to reclean, and a volume check; most problems are simple in balances between left and right injectors, which then causes funny out-of range idle and off idle problems. The Ford CFI self compensates pretty good, but the system is dependent on a good standadrd of wide open throotle fuel flow, and a stock squit pattern, with proper fuel supply stops during pulsewidth modulation.
Fords suppliers really did a good number on sourcing Bosch style injectors with exceptional quality, but its nothing for one to flow +/-10% of the other, with more than that difference common in practice.
