Update..
I went thru the entire wiring and gauge and determined the gauge itself was faulty. I have since ordered a new one from Lexus. Interesting thing midway thru the 92 year Lexus changed the gauge design. Now if you have a first half model year the the gauge is about $115 or so but the second half model year it is $290. Lucky for me mine was from the first half.
There is a slight difference in the needle but not much. Now the gauge reads fine so far and goes to zero when you shut off the car. I will see how it goes and if my issue reoccurs i will post.
Thanks for your replys.

I have a 2007 lexus is250 that has approx 140000 miles on it. I just got it back from the dealership after they finished installing the new pistons. I just wanted to know if i can add a can of bg 44k to the gas tank? Will this harm my fuel filter or have any bad side effects, since i never use a fuel additive before.

Why did they replace the pistons? And why do you feel the need to run that product through your fuel tank? Though generally they will not really do anything of interest on modern cars, they are peace of mind...for some at least. Detergents in modern fuels negate the need for fuel injector cleaners or anything of the sort.
You would likely be better off running seafoam through the vacuum system.
But again, why did they replace your pistons?

The IS250 had a flaw with it pistons design causing major carbon build up issue leading to rough idle and rapid oil consumption. Lexus issued a warranty to extend coverage for the pistons replacement. Thanks for the response. The dealership I go to was advertising it and i've heard some good stuff about BG's products.

As a side note, fuel injector cleaner will not help these engines... Seafoam or intake cleaning treatment is the only real help for this issue. This should be administered through the closest vacuum port behind the throttle body that has the most even dispersion in the intake manifold...
