Blindly replacing parts is about the dumbest and most expensive way to repair a car. There must be stored error code/s if your SES light is on and the stored codes will tell you where to start doing your diagnosis and the GM repair manual will have the diagnostic procedure. Get a scan or a scanner and a GM repair manual and use it.

Even a paperclip will get you better results than guessing
