Quickie 3rd Gen idle speed ? after cleaning
Since I had the intake tube off yesterday while changing out the spark plugs, I decided to go ahead and clean the throttle body/butterfly. I used CRC cleaner and went to town, being careful not to tweek the butterfly, etc. Got a good amount of black buildup out of there.
My question is regarding the idle speed. Is it normal that the engine will run at a higher idle speed for a while after cleaning the intake path? It initially ran at around 1,000 RPM or so yesterday and this morning, but has now settled back to its normal 750 RPM or so. Should I have simply disconnected the battery for a few minutes following this?
We have also had a few days of weather in the low teens, but that would not explain the high idle after some extended driving.
Again, all seems well now, but I'm cuious what may have caused this temporary jump in idle speed.

I have had the same thing happen on the Runner and other vehicles after a TB cleaning. Do I know the physics behind why it happens? No. But, I can tell you that all the vehicles are alive and kickin to this day.

Very technical I know, but I hope it helps.
