1982 RX7 Gsl 2 cylinders not firing?

[sunup420]

During idle the car seemed a little rough I checked the spark.On two cylinders I noticed no change in the motor when I disconnected the spark plug wires the other 2 made a change.Good spark to all plugs,whats up any thoughts.Thanks 1st Mazda love it.

They only have 2 rotors.... 2 plugs per rotor

Unless he\'s pulling trailing leads of which would explain the no diff on idle.
