While I can't say I've never done the same thing, I will offer that I try hard not to do it anymore. I've been sufficiently frustrated by the poor results and high cost of the shotgun approach that I now strongly believe in diagnosis and analysis.
Perhaps a local parts store has a tool loan or rental program you can take advantage of? If not, let that test slide, and concentrate on the other issues first. And remember, the ECU will need an hour or two of drive time to self-tune itself, so it may well be a little off until it has had time to tweak its fuel tables.

That's not much use, I'm afraid. You really have to have the jumper in place to get or do anything worthwhile.

Not really. All engines seem to do that, even when the fuel is injected two feet downstream of he throttle blade. Besides which, there's no combustion in the intake manifold, so any fuel present there would be raw gasoline, which would wash the throttles, not stain them black with soot. The soot is from oil vapor, which comes from the crankcase.

I'd look at the other things I listed before worrying about compression.

Good to know there is some combatibility there. Thanks to mr220v for jumping in again with some useful info!
