Somebody recommended putting a sniffer on the exhaust. I have found a local shop that may be able to get a CO2 machine on the car for me...
Will that help me in any way figure anything out?
I think I will unscrew the O2 sensor and just physically feel if it heats up instead of guessing regarding the voltage on the wires.
