Universal Oxygen (o2) Sensor From Ebay

[Trav33]

I bought a universal O2 sensor from ebay seller enginesensorsandsystems. Worked awesomely for 6 weeks - got fantastic economy... but then it dropped off week by week, and I am back to where i started - maximum of 350km per tank.

1. Has anyone bought an O2 sensor from this ebay seller? Was only $50 i think.

2. Anyone used universal sensors successfully before?

i would think that anything over 300km is not to bad, when mine o2 sensor was rooted i was getting around 250km

If you are running rich you could be fouling your new O2 sensor?

Yes, true!

So i was running rich, getting 340L/100km.

Changed O2 sensor, got 460L/100km, so not running so rich anymore.

But now i'm back to 340L, and would be running rich, and fouling the crap out of it....

It seems like the worse the economy gets, the more fuel going thru the exhaust, and the more fouling and the worse the O2 sensor works, and the worse the economy gets, more fuel, etc etc etc - its a vicious loop????
