Check and clean the ground connections: transmission, engine (valve cover), thermostat (main ground for ECU), car body, and negative battery terminal
Maybe the engine coolant temp sensor or MAP sensor.
Describe the idle
-when engine is cold
-when engine is getting close to operating temp
-when engine is at operating temp

I'm with ChrisS, Coolant temp sensor. If I remember correctly, it is screwed into the thermostat housing. it's a pretty cheap part. It it fails, it sends the wrong temp reading to the ECU and the the car adjust the timing to compensate for an incorrect temp. I've swapped mine twice.
