Idle Fluxuation and Popping

1987 930 with Fabspeed exhaust.,

What is causing the idle to fluctuate when you downshift and stop at at a light. RPM is up and down and the engine sometimes stalls. It usually will correct itself after a 10 seconds. Also, backfires (Pops) at a constant rpm or deceleration. I had the mixture adjusted a while back and this was the outcome. Car runs with a hunting feel at a constant RPM. Kind of a small lurching feel, Not a smooth feeling...

Help fellas what do you suggest?

THANKS

Bob
