Try using some spray Berrymans carb cleaner and spray around the intake

you've found a vacuum leak.

I seen or read about also using a propane gas from a small tank. Just
open the gas valve an point to the suspect line. RPM gets eradicate.

Yeah, that's what I did. I even put a hose on it so I could tell where
the propane was going, and I put it everywhere in the intake area two
pieces met, rubber, metal, whatever, but nothing changed the RPM.

I didn't want to use carb cleaner because the engine is almost spotless
now and I figured it left residue. Is carb cleaner going to work
better than propane?

This guy used carb cleaner. No luck. But he found the leak with his hand.

Well if it was good enough for him, I tried it a couple hours ago with
the engine idling, after I cleared the codes

I put my hand everywhere and couldn't feel any breezes.

I also tried squeezing all the hoses. None of them felt mushy or seemed
to be cracking, or seemed loose, or affected engine speed, and most look
like new. (Especially the large pleated? corrugated? hose between the
air cleaner and the plenum.)

Then I got in the car and drove. In the past it took no more than 10
miles to set the codes and for a while it would do it in 1 or 2 minutes
of idling. I forgot to look at pending codes until 6 miles out, and I
had not only the 0171 and 0174, but I also had 2198!!!

But after 4 more miles, there were no pending codes anymore, and no
actual codes. And after 10 more miles to get home, still no codes.

Plus, the engine doesn't seem to hesitate anymore, though maybe I
learned how to accelerate to avoid that, and it's hard to go back to a
style that was causing trouble. (If that's it, I"m sure over time, I'll
revert to my old style.)

There are a lot of hoses, but if this starts up again, I'll go through
them more slowly and more deliberately

Oh, I found out what p2198 means: "Stop squeezing my hoses."

Code p2198 means" Stop squeezing my hoses or I will sue you for hosual
harassment"

Actually it means "O2 Sensor Signal Stuck Rich Bank 2 Sensor 1"

and this reminds me that last night I sprayed the base of the B2S1
sensor with PB Blaster, since changing the sensor woudl be easier and
changing the manifold gasket. I only sprayed where it screws in. I
saw what got wet and the top didn't. How could spraying the base affect
*any*thing? Especially since it was 20 hours earlier.

If the codes come back after the stuff evaporates, I'll spray it again!

Also should mention that I used the tank with Techron fuel injector
cleaner in it, and yesterday I filled the tank and put a can of Sea Foam
fuel injector cleaner in it. But the car has always been able to do
70mph without stumbling, so doesn't that imply the fuel pump was good
and the injectors were clean enough?

I havent' tried to accelerate up a hill to that speed because I haven't
seen any hills.
The Techron may have cleaned the injectors enough that they are no
longer running lean - and it may have happened suddenly enough that it
temporatily ran rich throwing the 2198. Might have been a problem
with the FP regulator too - fixed by the Techron.
