1988 Idle Surge

I have a 1988 4runner with the v6. I had an idle surge on hot starts that would go away after a hard acceleration. After removing and cleaning the intake the idle surge now occurs anytime when the engine is warm. The odd part is after a long drive on the freeway it idles fine for a couple minutes. Ive played with the idle adjustment, idle air bypass, TPS, and listened for vacuum leaks. I'm at a loss for what could be my issue, EGR? O2 sensor? Magic? Any help would be appreciated!

 

Many years ago my 1988 (22R-E) had similar symptoms. If it's the same type airflow meter, squirting WD40 at the pivot points made it go away. Mine was just binding a little, apparently. It was an easy 'fix' that lasted for months at a time, so I never pursued it further.

 

Didn't work still have idle surge once its warm.
