Update here: Pulled all the injectors, had them sent out and cleaned. Guy said they were all fine anyway as far as flow rate, atomization was improved but in general they were fine. Getting the injectors out of this motor is a total PITA, by the way, and I've done pretty much all the big E39 jobs so far. The little clips on the injector electric connectors are one of the most maddening items on the whole car.
Anyway, put a fresh tank of gas in, gave it the business and bam, same code. C5, misfire w/fuel cutoff Cyl #2. DAMN! Also got a D5, Cyl 5 misfire during warmup and a 95 - Misfire w/empty fuel tank but the last two codes I'm guessing are simply from starting the car with empty fuel rails after the injector reinstall and are unrelated.
I'm done with this thing at this point, giving it to a shop to take a look at as a next step. I'm out of time and patience.
