first thing that came to my mind was amm, i know you did the 4 sec, but while the car is at idle and motor at operating temps. unplug the amm see if there is any change in the motor.
then check the motor harness plug to the amm, make sure the inside prongs are pressed close together and spray inside this plug with electric cleaner (spray in a can) and also spray the amm prongs the harness plug connects to.
there may be a deep rooted issue like a bad injector, but amm came to mind when reading your post.
