While on the highway yesterday, I noticed that the check engine light ( outline of an engine) on the dash came on and started flashing (blinking) for about 25 seconds then went out and didn't repeat. At the same time, a small orange/yellow "car figure" appeared on the dash as well. It went from yellow/orange to green. Can anyone tell me what the issue may be on the engine light flash? I'm going this morning to have any codes read.
