theres an easy way to check this, remove your air intake duct from the throttle body, start you car and let it idle ( this should be done when the engine is cold) there are 2 holes in the throttle port the top one is for the idle air control valve (IAC), the bottom if for the fast idle thermo valve (FITV). plug one of the holes with your thumb. if the idle goes back to normal when you plug a hole replace that part (top hole IAC, bottom hole FITV) NOTE: these parts arent cheap, sorry bro.

Its your IACV. Take it off and clean it.

stopping on its own means nothing. What it did was because of the IACV. Do a Search on it and see. Take yours off and clean it up.

First the hose with liquid in it is coolant and should NOT be hooked up to a cai.
Dremmel and make a straight cut on it and use a flat head.

Soak the lower part in carb cleaner. Then put a dab of wd40 in that area to lightly lube it

I have a question along these lines.
I parked my 99' TL for 3 weeks and when i got back, the battery
was as dead as a door nail. Turns out the RR door was ajar and drained
the battery dry.
I had to give it a 10 minute charge off of another car and then use that car
with the engine running to get the TL to start. When it did, it had a mean
hunting idle (up/down--repeatedly) but it went away after driving it for an
hour on I78. Before it is suggested, I cleaned my IACV about 6 months ago
when the weather was nicer than it is now.
The hunting idle is gone but why did it do this in the first place?

Not that the IACV was a tough job but with old man winter on the way
I wouldn't look forward to working on the car, heated garage or not.
