No one's said IAC? I know that's pretty much the catch-all when it comes to idle problems, but...

I have the IAC restrictor on mine, when it's extremely cold (20 or lower), it nearly stalls, but then catches itself. I don't think the IAC is opening fast enough... and this is on a car with ~40k miles. If you have more, it's likely the thing is just worn out/lagging due to the cold.

I can clean the IAC with what.

my car wouldnt idle and it ended up being the IAC, so i went to auto zone got a can of carb cleaner took the iac off sprayed it down then i made a new iac gasket and car idles fine( around 750 RPMs) cost me all of $2 and about 10 min to figure out the right size hole for the iac gasket.
