This is not a project, moving to tech.

I would check the wiring to the front 02, they can last 100k or more with a properly running car. I would check the o2 heater circuit and signal wires to the PCM. I would think with OBD2 it would be harder to fool the computer on the primary o2, the narrow band simulation worked great on the obd1 dsm stuff for sure.
