Hi, been a while since I was last here...life has been insanely busy and our 2002 CR-V has been soldiering on, a bit thirstily, but...145,000 miles. Anyway we have the 'D' light occasionally coming on, flashing. Pull over, turn off restart it's gone for a couple of days or a week. I've read, and watched much about what it might be on the web. Anyone had this?
