2008 GMC ENVOY Power Train Problems

CHECK ENGINE LIGHT IS ON. ACCORDING TO TESTS IT IS THE RESULT OF A DEFECTIVE THROTTLE POSITION SENSOR. THE LIGHT WILL STAY ON FOR A COUPLE OF DAYS AND THEN GO OFF FOR A COUPLE OF DAYS CREATING A ERROR MESSAGE THAT SOMETHING IS WRONG WITH THE ENGINE. WITH IT GOING ON AND COMING OFF IT IS NOW DIFFICULT FOR ME TO GET MY INSPECTION COMPLETED WITH THE SENSOR READING NOT BEING ACCURATE. *TR
