code 16

I have a code 16 and my car will not idle and only starts once. It is a built b16 with turbo and 450s. The car was running fine and then just crapped out on my while I was tuning it. Xenocron says that 16 is a bad connection. The local honda shop says that it is the fuel injectors. I have checked all and everything gets power. What else could it be and what procedures do I need to go through to find the problem. I have removed a vafc from the car but never had any problems till now. I have check voltage to the map on the ecu and the sensor. I did have some bad connections but they are fixed now. Any thoughts?
