This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

Fix that wire before you cause damage to your catalytic converter or worse. The sensor is important for the engine to calculate the proper amount of fuel it has to inject. Too little (lean) and too much (rich) are both detrimental to your engine's well-being.

Oh yes. Had literally just happened. I'll swap it out soon.

Narrator: he never replaced that O2 sensor, but the catalytic converter never suffered any direct consequences either, despite all the dire warnings from Lemmy, since the thief who stole it kept it safe from any unburned exhaust gases.

Jeep, the converter is probably just fiberglass and wasp nests
