Thanks for the help
There are some problems with Altima and Sentra 2.5s having TB getting excessively dirty. You should just clean it out with a good rag soaked with a mild detergent and water. DO NOT let any water drip in (well you can let a little, very little get in, but just try to be careful and not let any). There is a teflon coating inside that is supposed to keep the inside clean, so using something like a chemical cleaner may remove that coating.
The service manager is correct in saying that you need the Nissan CONSULT to reprogram the ECM to correct the idle speed.
The idle will go up after cleaning out the TB, and this may set off an idle speed control code in the ECM. But the ECM will readjust the idle on its own. You may have to live the check engine light being on for awhile tho.
