Hi fromaz2va,
Sometimes sensors work inaccurately and the ECU is not smart enough to understand it. The light might not have come on and a scan will see whether there is any which you might not have noticed. The best way is to get a diagnostic done.
Most probable causes are the TPS and MAP/Mass sensor. However this is a drive by wire model, you need to look at the pedal side too.
