i was told the ecu is constantly changing the air fuel mixture so the lights should actually bounce back and fourth. It should be at rich when at WOT and it should go lean if you are driving and take your foot completely off the gas. thats cause the ecu leans the air fuel mix to help slow the car..........just my 2cents...you have a turbo so i assume it will be different for you...
