No codes surprises me. That tells me either someone took your bulb out of the SES light, or the PCM isn't requesting OD for some reason.
What RPM do you run at 70?

Will, would TPS have a play in this?

It could. But if I recall, the MAP and the MAF also do. There are alot of factors on the OBD2 cars with the 4T65E. It'* over-managed to the extreme by the PCM.

I received a TPS code about a year ago and replaced it with an AC Delco.
I have a code now for misfire in #6 on another thread, so the service light is there and works.
I should take it in for an expert to look at. I have had the codes cleared, unless there is a hidden code....
What is the TCC?
Rpms at 70 are about 2800.
