'89 200TQ Ilde Fixed (I hope!)

[Todd Joseph <todd@ConnActivity.ConnActivity.com>]

Thanks to everyone on the list for their help.  Especially, Bob Myers
who responded to each post I made and and Lee Levitt who recommended
Central Street Garage to me.  They diagnosed and repaired the main
problem in less than 2 hours (intake boot).

My '89 200TQ is finally running well, very well.  

I had my '89 200TQ towed to the local mechanic who inspected and
replaceed the intake boot (along with fouled plugs).  This resolved my
problem with surging.  

He didn't adjust the mixture, so I assume the car is still running a
bit rich, and possibly set to idle a bit high.  Not sure what to do
about that.  Suggestions?

On my way home from the mechanic's shop, the RPM's would drop to ~500
and then bounce back to ~1000 when I engaged the clutch.  I had
already received a new ISV and Oxygen sensor from Blau, so I installed
them.  The ISV was easy to swap.  I had to buy an oxygen sensor socket
to remove the oxygen sensor, but after that it wasn't too bad.  Did
the air filter while I was at it.  The tip of the old oxygen sensor
was a bright white and was somewhat rusted into the block.  I bought
one of the A/C Delco Oxygen sensors from Blau which was a simple
install -- with *no* splicing.

After I installed them, I took the car for a brief drive.  It ran fine
leaving the driveway, and going to the first stoplight.  As I left the
light and shifted from 1st to 2nd, it bucked quite a bit and then
continued normally.  

I brought the car back to the driveway and disconnected the battery
(to reboot computer), and started praying.  ~5 mins later I took it
for a drive and the bucking was still there.  Expletives.  Brought the
car back and proceeded to clean it (vacuum) and ponder what I should
do next. In-laws stopped by, and I chatted with them for a while (all
this took about 2 hours).  

Went back to the car thinking I'd put the old parts in.  Took it for
one more drive (more praying), and the car ran beautifully.  Idles
between 900-1000RPM and accelerates better than I imagined possible.
Drove the car for over 30 minutes with no problems.  Drove it again
today for 30-40 minutes, again with no problems.

Is this normal?  Should I have done something special when I installed
the ISV?  Oxygen sensor?
