I Have a 90 Legacy GT, I have just changed all spark plugs and replaced 2 of the ignition coils. The engine is still missing when warming up. Does anyone think this rough idling (missing) is being caused by the Air Flow Sensor the check engine light is not on. Can anyone shed any light on this it is becoming extremely frustrating

My 1990 GT Legacy is missing in particular while the engine is warming up. It starts well from cold and idles okay for a few minutes then it starts to miss. I have had the sensors checked and cleared - the sensors are okay. If you really put your foot down on the gas it seems to stop this. Does anyone else think that this could be a ignition coil problem?
