SES light flashing and rough idle, fixed itself?

While idling at a gas station, my ses light starting flashing. The engine starting running rough... I drove about 2 miles and called the dealer telling them I was bringing it in. Turned it off and sat for about 20 minutes... Started the car, then it runs fine and ses light is off.... I am all like all wtf? Drove it to the dealer. They hooked it up to the computer, no codes and it is running fine for the last 3 days. Timing chain was just done, no issues when they test drove it after that was done... Maybe mass airflow sensor is acting up? Dealer said the mechanic can't find anything wrong and to drive it... Has anyone else has this issue?

bit of a rabbit hole to go down. could be a number of things: petrol sender in tank, petrol rail, manifolds, sensors, cats, MAF, fouled plugs, etc.
 
I know..... Hopefully it doesn't happen again. It hasn't since I picked it up on Friday... I guess I will just keep driving it..
 
I've the light is flashing and you keep driving, your flirting with an expensive disaster. Get the codes read by a qualified mechanic. You didn't tell us the year of the vehicle.
