Wideband erratic

Ok, so put my fast dual air meter in. The thing is just up and down like a yo yo, almost impossible to read, both sides.
I'm gonna try single sensor tomorrow. Also tried the rpm module in both the msg 6al and round the injector lead, that's the same? Any ideas anyone. I've the rpm module can be a PITA but not the actual wideband reading. They are in the collectors Hooker super comps 6228HKR. Can't find any leaks in ball and socket collectors or flanges.im sure this is not engine related as new build and the meter did the same on 5 minute install on old motor. I thought it may be due then to having them mounted just before cut/outs and it was bouncing back from the "dead end" this is a whole new system, headers 3" 1 chamber exiting before rear tires.
Taking power from 12v accessory port/cigarette lighter. Sensors crapped out?
