Asia:
Turns out my idle surge (bad choice of words--more accurate would be a steady high idle of about 1200rpr or so)--was caused by a SMALL slit in the new hose I installed. The hose from the small pcv grommet to the throttle body. Turns out that once the engine got warm, the hose sort of expanded at the throttle body nipple, allowing unmetered air into the throttle body!
The wierd thing is, the car and idle were fine for about the first 5 miles or so of driving--just long enough to generate heat, swell the vac line, and send the idle up about 300 rpm (steady). Happened each and every time I drove the car after it cooled down a bit..
The hose I had used was the type that had rubber in the center and some sort of braided stuff on the outside. Switched it out to a piece of silicone hose I found in my driver's seat seatback (my spare parts location !!!). Haven't had a problem since then, and it's been awhile.
Now, I just have to get up the courage to go get the smog test. I think/hope I'll pass now.
