Today on my way to, and on the way home from work I am getting an intermittent check engine light. It will come on after 5 minutes of driving and stay on for about 15 minutes. When I stop the car it goes off. Does the ECU hold the codes for any length of time or do I have to get them with the light on ? Any other ideas greatly appreciated.
