Fark! I had a long post written up and I hit "delete"...
First, sorry if I seemed harsh. My mistake on the NTC. I can relate to the late night diagnosis (and work schedule...) - and street/exposure to the elements mechanics. My mini maglight shows all the teeth marks and drool from those sessions.
I recently replaced my TPS when I discovered it no longer registered a wide open throddle signal (while testing all the APC components). The Bentley multimeter tests are very straightforward. The simplest test is to listen for a light click when you just crack open the throddle.
If an intermittant vac leak is causing the high idle it's a weird one. I would suggest a component such as the APC pressure transducer or overboost - just because most flakey vac leaks open up due to boost pressures. You can test these by applying vac to the hose from the intake that goes to the firewall under the brake fluid res (generally). Another obvious one is the thicker rubber hose on top of the charcoal canister. Mine was very cracked and loose when I replaced it along with all other lines.
On a related note to the AIC - If you have access to any junkyards, its a good idea to grab an extra AIC and AMM. It helps to have spares when diagnosing.
Good luck.
