New VX O2 sensor installed

[GasSavers_James]

I put a new L1H1 O2 sensor in my VX today. I had to use a cheater pipe to get the old one out, but I did it and didnt break anything. The technique was to cut the wires on the old one so I could get a nice long socket over the sensor. It was a gamble but it worked.

It seems to run more smoothly in lean burn now. It used to miss a little in lean burn before. It can smoothly accelerate from 1200rpm, which is a great thing. The transition between lean and regular is less severe. It also seems to have a little less power when you give it some throttle now. I also reset the ECU so that may have something to do with it.
Unfortunately when i did my compression test, my wife left the ignition on for 6 hours, running the battery down. I charged the battery, and it seems to hold a charge (it wasnt quite fully drained). Luckily nothing serious seems wrong, and hopefully there are not any damaged components.
I have noticed that sometimes when putting it in neutral, it drops to 750 (like normal) and then goes up to 1200 and back and forth 4 or 5 times. I dont like the looks of that and wonder what that could be. Anyway i wont worry yet because it only happens every once in a while. Actually it only did that a couple of times before, when it was still warming up.
Hopefully, the smooth running lean burn will help lift the MPGs...we will see.
