You may think there is nothing wrong but there is. If the check engine light is on there will be codes stored in the ECM. Have the codes read. The codes will help you determine what the cause is.
A clogged fuel filter can cause a Mitsubishi Galant to idle rough for the first 10 minutes it is running and then it runs fine after that. A fouled spark plug can also cause this issue.
this is caused by the sensor tripping in the light sensor to see what causes this you must diagnose it with a computer and see what fails in it.

A late oil change will not cause of car to lose power. Oil is used to keep the engine components lubricated. The lose of power may be coming from the car running to lean. Take to the car to receive a diagnostics test.

ECM will not cause A/C to not work properly. some of the earlier mitsubishi's had a ground wire for the A/C going through the ECM. and i have ran into the circuit in the ECM that grounds it go out causing the A/C to not work on a few diffrent cars
