Any ideas as to why when cold the idle is rough? Once temp gets close to 180 degrees it smooths out?
Here's what I did that preceded the symptoms:
De-snorkled
Ran 1 tank with Regular.

Have since re-snorkled
Ran at least 3 tanks with normal premium gas.


Cleaned the throttle body, which initially remedied idle problem (for a few cold starts) and then went back to rough while cold idle.

Particulars: 2002 Boxster S, Tiptronic, 66K miles.

Any ideas?
