One more thing Steve, I can't remember how early or new your = EC2=20 is.   The early instructions had an error in the EC2 to = PCM=20 connections.  Corrected instruction were sent to all affected = users.=20
The version in error showed pin 10 on EC2 going to pin 10 on = the=20 PCM.   Check this out and make sure it's not in = error.

To make any meaningful comments I'd need to know if you = tried=20 the easiest things first.  If the engine is running too = rich,=20 did you turn down the mixture control? If so, what = happened?  If that wasn't enough, did you reduce the = injector=20 flow rate?
