    19’ Taco 38K miles. Did some reading and I have 2.7ohm load on front O2 sensor and 6.8ohm load on cat O2 sensor. Odd these would go out at the same time. Any one know if those reads are good?

    Swapped the fog light relay and A/F Heater relay around since they are the same to check that already and code didn’t clear.
