the screw wouldn't make the idle jump just high or low but if you place this in the engine tech forum you might get a bigger and more informative response.

hmm

There is no ac in the car... and it only seems to do it when the car has warmed all the way up.

when it's at a stop light it does it or any time the car is at a idel.

how fast does it surge? vacuum leak is the first thing that comes to my head. but if your coolant is low, air pockets could be going through the fast idle valve causing it.
