HID headlights by any chance?
I've got one sitting in the barn off of my ws6.. I'm in Indiana.
that white WS6 with the CCW's is freaking nice...love that car.
For some reason when my 98 worked the idle was around 900-1000 rpms even with a Frost tune. I have a LS6 intake and P&P S2 Throttle body.
check grounds work on the alternator lately?
