The ck engine light should not be ignored, what sensor was shown to be bad ? Have it scanned again and replace the sensor that is bad if it still runs rough you might want to consider a tune up. Plugs, wires, fuel and air filter's and clean the throttle body with some gumout. It could also be the IAC motor Idle Air Control. Good Luck
