My ETC light came on at a stop light. I shut the car off and it went fine. on 2007 Dodge Caliber

Is this something I should worry about?

this happened to myself a couple of weekends ago while driving down the coquihalla to vancouver
the car lost any accelator control and ran really rough we pulled over and checked the manual and it said it was ok to drive and did not need towing
we went to can tire and were told we would have to go to the dealership and it was a sunday
so we wiggled to petal and started to the car and it has been fine ever since however i do smell gas lately...near the car
have codes scanned to see what malfunction happen at that time
