Do you have an OBD reader? Something to tell you what the ECM thinks is wrong and thus causing too rich A/F operation?

Yes and no. The ECU pretty much refuses to throw a code unless unplug something it can throw a code for, BUT I can watch live sensor data. See this thread:

I attached a datalog of what the ECU is outputting.
I'm using CarTester8000StableEdition_English, going to file-> view and viewing the .ctr extracted from the attached zip file.
PM me if you just want me to send you a dropbox link to the program.
