Agreed on TB.
I had intermittent warm no-start and idling issues an when I got my 99 Viggen, never threw a code. Replaced just about everything in the fuel delivery and ignition system except for the injectors and TB, including the various sensors you mentioned. I cleaned the TB thoroughly and ran injector cleaner, no luck.
Finally put in a used TB from my indy, which solved the symptoms but subsequently failed in traffic (and threw a code). So I got a credit toward a new TB unit, and haven't had any of those issues since. Moral of the story, if you've spent the money on all those other new parts, don't skimp on the TB. I can't vouch for a rebuilt unit (BBA) but that might work too (if you can get a loaner TB or don't need to use the car for a week or so).
