I think I got all the good (plus some) out of the original '95 HEGO. It was still working, but it had broken a few branches that I ran over (some that were still alive & connected to live trees), and I thought it might be part of my exhaust leak. The new one (MotorCraft DY-733, Ford F4UZ-9F472-CA, Bosch 0 258 003 5367537) cost ~$35 shipped from eBay.
