That's pretty complicated since the tempurature under the hood
shouldn't change all that much with the weather once the car's warmed
up (or so I would think).
I suggested the throttle cable slack privately to Hoon, then publicly
to Robert only to discover that someone else had publicly posted that
already. I'd try the easy things first (loosen a single screw, give it
a little slack, tighten the screw again).
