It's also possible you may just have a weird DME fault causing this - the MS43 has a barometric sensor on the DME board and I've seen similar issues with an MS45 with a barometric sensor problem. The sensor didn't fail - so no code, but it was faulty - the result of this was the erroneous data fed to the DME messed up the fuel trims. The car I was working on would throw consistent O2 sensor codes after enough driving.
There's nothing wrong with creative solutions, but this isn't a solution - it's a bandaid
My advice...

First and foremost, stop doing this. Let it set a code and go from there.
