Description: Radio Interference From Ignition Coil(s)

Symptom: "With radio tuned to an FM station, a popping noise comes from all speakers when the engine is running."

Probable Cause: Weak spring tension on one or more of the ignition coils allows a gap between the coil and the spark plug. Arcing across this gap cause radio interference.
