2001 3.4L Olds Alero.
I had someone else (who does work on cars) watch the spark and he said it was not a steady spark and said it was a bad ignition control model so I replaced that and nothing changed.
I did have a EGR P0401 Code a couple of weeks ago but after taking it off and cleaning the valve and port the code went away and the car ran great. Now I'm not getting any codes.
Both times it died on me the engine was running, shut off and then wouldn't start back up.
Thank You
