2001 Mercury Cougar 6 cyl Front Wheel Drive Automatic 140000 miles
This is hard to describe. It sounds like a low-power dirtbike engine sputtering outside the car. The noise disappears during acceleration and during idle (which the engine takes a minute to fully switch to idle). When the engine heats up, the noise occurs less and the engine switches into idle faster, but a light on my dashboard clicks on showing a picture of my radiator with a fan in the middle of it. At a friend's suggestion, I had the mass airflow sensor replaced, but the problem still persists. Any ideas?
