Yeah I was thinking about making my own code reader too.
There are some circuits out there. And I've got a laptop that I can use.
I think I'll call Napa or Lordco to see if they have a free or cheap service like that.
thanks for the input.
I did read something about the light going away after a bit
when someone had done the dyno thing on their car and the same happend to them. I think it must have something to do with the front wheels turning but not the rears.
I'll give it a couple of days.
