I think I found the problem.... or at least Tracy did. He realized that my symptoms would be a lot like what you'd get if you used peak & hold resistors without the 5 ohm resistors. 
 
About 2 years ago I got 2 purple 550cc injectors from Bruce. They were Saturation type, so I didn't need resistors.
A year later I got two more from the local Mazda shop for the secondaries. They were purple, so I ASSumed they were the same. I tested them tonight and found that they're the peak & hold type. Without resistors they get too much current and they don't open and close as the EC2 expects. Result - uncontrollable mixture problems.
 
OK, so how do I get 2 * 5 ohm 25 watt resistors on a holiday Saturday?
