88 240 Interesting idle stumble 200 1988

So, here is the scenario....

Arriving at a stop the idle will be smooth for about 10 to 15 seconds, then an intermittent stumble will begin to occur. Leaving away from the light, the car performs normally with no hesitation. Acceleration is good and under steady load the car feels normal.

Recently replaced items include FPR, vacuum hoses, flame trap, plugs and wires.

I believe this car sat for a period of time before I got hold of it, and has about 230k miles. I am thinking of having the injectors cleaned and serviced, as the symptoms seem to point to poor fuel atomization at idle, when fuel pressure is at it's lowest.

Is my logic reasonable? Any other suggestions?

Thanks,

Aaron
