MY TRAC OFF AND CHECK ENGINE LIGHT CAME ON AT THE SAME TIME. AND NOW MY CAR SHIFTS VERY HARD. AND IT ACT LIKE IT DOESN'T WANT TO CHANGE GEARS. I WENT AND GOT A DIAGNOSITIC TEST DONE AT ADVANCE AUTO PARTS. AND THE CODES CAME UP THAT THE VACUMM HOSE MAY BE CRACKS AND THAT I HAD A BAD GAS CAP, MY MAP SENSOR IS GONE, SOMETHING ABOUT THROTTLE/ PEDAL. AND THEN I HAD A DIAGNOSTIC TEST DONE AT ANOTHER PLACE AND THEY SAID THAT I HAD A SHORTAGE IN MY WIRE HARNESS. SO RIGHT NOW I AM CLUELESS ABOUT WHAT IS WRONG WITH MY CAR. NOT TO MENTION AGAIN IT IS A 2003 CHEVY CAVALIER.

THOSE ARE THE CODES THAT I GOT AT ADVANCE. THE OTHER PLACE DIDN'T GIVE ME ANY THEY JUST SAID THAT IT HAS A SHORTAGE IN THE WIRE HARNESS.

My suggest is to have a professional look at it. You may have some serious electrical issues. If you not sure how to look for it, I would have someone look at it. Or you can purchase a scanner and repair manual here and I can try to walk you through it.
