Hi! I've been having issues with my 2.5 legacy lately. It happens at random and maybe once every 3-4 weeks. Very odd!! At idle at a dead stop the car will just randomly shut off. Before it does shuts off the CD Player starts to act, the clock flickers, and car slightly shakes, the check engine comes on then the car shuts off. It takes multiple tries but it starts again. Then the check engine goes away, the car drives great, then 3 to 4 weeks it happens again... I did have the cat replaced 2-3 months ago. It was replaced with a used one but still costed my a good penny. I was told that the car was a California car and had the special CA cat..not sure if this could be causing it? Could it be a lose ground? Thanks for your help in advance! -M
