2002 Oldsmobile Aurora

MY 2002 AURORA V6, RPM STARTED ACTING HAYWIRE IT SHOT UP TO 8 GRAND AT 30 MPH. THE ENGINE AND TRANSMISSION WERE ACTING NORMAL. IT HAPPENED AGAIN 2 DAYS LATTER THEN ALL OF MY DASH LIGHTS AND HEADLIGHTS WENT OUT. I TOOK IT IN TO THE SHOP. I HAD THE TRANS VACUUM SENSOR CHANGED ALONG WITH THE HEADLIGHTS. THIS DID THE TRICK FOR 24 HOURS. NOT I HAVE THE SAME PROBLEM AND THE DEALER CAN NOT FIGURE OUT WHAT IS WRONG OR HOW TO FIX IT. CAN SOMEONE HELP WITH THIS. *TR
