2G TPS voltages issue help

[dmaffo]

Finally got my car started and noticed my tps is off.
Tried dialing in as per video on link site and previous experience with link v3. But something is off, no matter how much I play with offset or scale I am only increasing .10 Volts at max or 1-4% throttle position gain or loss.
When I try backdoor for the tps adjust on data logging screen it wont let me because of the lack, thereof VOLTS! it should be min 3.25 v or so. Not mine.
Any suggestions?
This was so easy before. Now that car is running not sure what happened?

awesome video thank you. I am here and after hours of checking so many different things I ended up running a hard wire ground just to make sure ground wasn't the issue and guess what? She works like a champ now that I grounded it externally. why I am not getting good source of ground through my plugs?
