I then sprayed underhood with engine running, and while there (after getting zero change in RPMs) I pulled off the MAF sensor plug. No change in idle speed the first two times, but it stalled when I plugged it back in on the third (while idling the MAF reads OK at 3.6-4.7, and rises when more air flow is ingested, so I think it's OK...don't know why I chose to unplug it).

...I looked at the Torque Pro screen and saw that my longterm fuel trims were zero'd, with the short terms at plus 18-20!!!...

Next, I looked at the Torque Pro screen (I had left the phone face down on the seat, while using the Foxwell), and was shocked at the short & long term fuel trims.

and saw that long terms were zeroed, while the short terms were ridiculously high (and I imagined I smelled gasoline, but got out and didn't smell or observe any).

So, I continued to observe the readings for a few minutes, occasionally raising the RPMs, and in awhile, the readings looked like this

...I'm very pleased with the fuel trims (I don't know how they got that way, but I hope they remain"normalized")....
