I remember that in the bentley (the O2 testing section) it states that if the DPR current is pinned at 10.2mA either the DPR or the ECU is shot (if you know that the O2 sensor is good and it's not causing the symptom). But that was for the CIS-E so I am not sure if the same holds for Motronic.

Cam chain timing is good (have 30 pics of it) timing belt good cleaned up and matched all 4 injectors cis-e changed motronic diaphragm regulator for a cis-e one (had gotten them mixed up) went back to old O2 sensor(one heater wire had fallen off so wired it as a one wire- black to green-(is this OK) went back to original O2 module reset the airflow sensor(all the popping pushed it back a little) replaced a bad cold start valve coolant temp measures OK same as before, hesitates and pops under sudden acceleration takes a couple of seconds(@ least) to get past 2500rpm idles great, past 3k rpm revs normally after a while DPR signal settles @10.2mA then doesn't move can't get DPR less than 10.2 no matter how much I enrichen my guess is that pressure in the fuel distributor is too high, too much fuel is sent mechanically and the O2 sensor tries to lean it out- when I started messing with the DPR settings it was +-18mA I have no way of testing fuel pressure. I'm thinking of changing out the diaphragm pressure regulator, Bentley says that a clogged return line is the only other reason for high FD pressure. Any thoughts, I'm usually way off.
