OK i have a JDM swapped F22B block on the DOHC setup. Car runs great till the temp gets to norm op temp. After that any time you come off the throttle the car stalls, and is hard to start. Have to hold accell down to keep it running. Timing is dead on, and no vacuum leaks or coolant leaks. Just did tune up with new plugs, dizzy, oil etc... Took the EGR, FITV, and IACV valves off and cleaned them thoughly. Still no help

I'm guessing that the coolant temperature sensor might be to blame, but you should check to see if the ECU is throwing any error codes first.
Here's how:
