General Air-Fuel Ratio

I have never seen a lm-1 semi permanently installed. I find it highly unlikely the wideband is the cause of any of your issues.

That makes some sense, and electrical part failures are often they work fine until not at all. Mechanical is usually (though not always) more gradual (except when things go “snap). An energized relay could fail by internal short on de-energizing, or the first moment of the next energize attempt, and it would do as described in this scenario. Think of a lightbulb going out: usually when you turn it on- POP. They are often easy to troubleshoot, too. Good call Kateare!
