Service Stabilitrack light on

[Geotrash]

I had the stabilitrak light coming on in my '07 for a while, and it was sometime, but not always accompanied by a code for either a misfire or a rich mixture on bank 1 or 2, or both. Can't remember now. Anyway, in my case it turned out to be the fuel pressure regulator, which is attached to the pump in the tank, going bad. I put in a new OEM pump and it solved the problem.

The trailer lights are wired and fused separately from the two studs, and are in place from the factory. There are individual fuses for the left and right trailer lights in the fusebox.
