Oxigen sensor change
That was very easy. The one I took out was an AC Delco and I suspect it was the factory original . So I put in a new Bosch sensor. I now feel that the milage is worse than before. The MPG readout in the digital dash used to read 13 mpg. Now it is 10 mpg. Anything else needs adjusting after the O2 sensor change? My wallet is running thin, very thin.

I changed mine a few weeks ago, I used an AC Delco.
I just scewed it in and connected it.
It seemed to run better with the new one.
One thing, I disconnected the battery while installing it, so the ECM can reset. [I don't know if this is necessary but I did it anyway]
Its also an outside chance they gave you the wrong sensor.
