Took it to my Indy and I guess my alternator was bouncing from 12, 14, up to 16 volts While running which was causing all the lights to light up like a Xmas tree. Long story short problem fixed and no more rough idle either. Stays at 600 rpms now. Hopefully by now you've solved your issue though if not hope this helps.
Did you get your codes read? Any ABS codes? Thanks
