What does it voltage does it say then?

No matter how light I go on the throttle it will read 0.035 or 0.050. And I don't see an mpg jump, UG can't detect L/B.
It might honestly be the fact that it hasn't had a tune up in probably 100k+ miles and the egr probably needs a good cleaning, along with an oil change, spark plugs etc etc. There is 198k on the car and I doubt the spark plugs or wires have ever been changed.
