WTK:any good RB mechs.RB cutting off in traffic

[themusician]

i have an S1 RB25DE motor.thing is there is a miss in the idle when the car gets hot.i checked the coilpacks and they seem to be fine.i did a tune up recently too.i took out the idle unit and cleaned it as well.when the A/C is off and the car is left to idle it sometimes cuts off.i did a diagnostic and all the sensors are good.other than that,the car drives just fine.can anyone provide me with some feedback on this problem??
