I've removed the TBs on three different Z's to clean them. Definitely moved the butterfly valves a bunch to thoroughly clean them. All I did after was the idle air relearn procedure (takes ~25 sec). IIRC there is another, more complicated reset procedure that should be done if the idle air relearn does not suffice.

I had intentions of not moving the butterfly valve while cleaning. But these cars had 35K, 50K, and 70K miles on them, and there was no way I was removing the line around the valve without moving it. I used a hard plastic toothed brush to clean them with great success.

Just did this today and changed plugs while I was at it. It really is pretty simple. Mine has 70k and by the looks of the TBs they have never been cleaned... My towels looked 1000% worse than the pic someone posted earlier.

I also moved the valves since they were so filthy. Started it up afterwards and didn't do the relearn yet (I had the battery disconnected anyway bc of pulling plugs). Idle seems higher than before so I'll try the relearn tomorrow. If you haven't done this yet is worth a look. I could not believe how much gunk and tar was in there.

The relearn should help drop the idle down to 650 RPM or so instead of 800 RPM. With the battery unplugged earlier, you'll need to do the throttle closed position and accelerator pedal learning procedures. Takes about a minute to get both procedures done.

IMO, there's not much to worry about moving the throttle plates. I've done it many times, which makes it easier to get to the hard to reach spots. I also added some thin lube to the shaft as well. One of them was squeaking earlier.

I did all resets and I think they took. Idle is near 700 again after warmed up.

A follow up question about the idle relearn reset... I followed the manual and all was fine until the part where it says to hold gas pedal down for 20 seconds until MIL light stays lit, but each time I did the reset it only took about 5 seconds to stop flashing. Is this normal?

IMO, should be fine. After the 7th second you hold down the pedal until the MIL light starts flashing (20 sec doesn't matter at this point). When it stops flashing and goes solid, you have a few seconds to quickly start the car and let it idle. Then you blip the throttle a few times and see the idle drop steadily as it warms up. I think you should be fine now. close to 700 RPM is not too bad compared to 900-1200 RPM lol.

After a few days of driving my idle has settled down to under 700 now (650 I presume based on previous responses). No more bogging down randomly while sitting at lights either.

So, you were right digitonium! Does not appear you have to continue holding the pedal once the MIL light stops flashing.

I disconnected the TBs and moved the butterflies on three different Z's in one day a couple years ago without issue. Just make sure you do the pedal position reset. See posts 41-43 in this thread for clarification.

Possibly not, but the reset is so easy to do, I would do it anyway.
