Well, the engine coolent temperature sensor should tell the ECU when the engine is warmed up and adjust the mixture leaner. Sounds like you are running a bit rich when warm. Do you smell gas at idle? But, it seems odd to me that it would take 45 minutes to get warmed up. Even 10 minutes would be a long time. Also, possible O2 sensor. Any other opinions from the group?
