Today my 986 died on the Bay Bridge

[Oaktown 986]

Ok, so I cleaned the MAF and replaced the Spark Plug tubes as an excuse to pull a plug, and because, well, it was needed. See pics:

When the MAF was pulled, a cloud of dust erupted, so cleaning it appeared to be a good idea. The spark plug pulling indicated nothing unusual, and the tubes' O rings were definitely in need of replacement, but alas.. the car still isn't running well. It has no power above 3k right now, but it still hasn't thrown a new code yet since I cleared the codes below.. any more thoughts on what to try?

Check to make sure that the butterfly valve in the intake rear is opening?

in the throttle body?

Booked 2 O2 sensors to NAPA with wiring included, pre-cats, on the recommendation from my neighborhood Audi/Porsche mechanic. I'm going to replace those tomorrow and see if I can't get 'er running respectably..

The rear cross-over pipe on the plenum has a butterfly valve that opens / closes with RPM, and I have heard that if that is not operating, as around 3K it really loses power.

That and fuel pressure would be easy things to check.
