it came on while i was driving about 5 min after warming up and i dunno for how long, but i barely caught a glimpse of it. it couldnt have been more than a second. on and off and it didnt come back on again...is this a warning for me to check my engine of just a wonkey light...

 

You can always do the CEL code check, but unless it goes on and stays on, I wouldn't really worry about it..
