B6 analog input issue

Hello,

Im using B6 Analog 2 input for my AEM UEGO wideband.
Grounded at Thermostat housing.

D10 ELD is being used by TC so not available.

When i connect wideband output (2.25v approx) to B6. I see the voltage continuously fluctuating from max to min and also effecting ELD voltage.
With nothing connected to B6 i read 1.12v

(see attached log)
R2 & R3 have been removed.
All help appreciated to solve this.
Perhaps i need to install IN4148 Diodes?

Is the ELD still connected?

Solved.
I moved to input D12 analog 1. All was okay.
ELD was disconnected.
