1997 Dodge Avenger 1997 AVENGER

I HAVE JUST REPLACED THE MOTOR IN MY AVENGER AND IM SURE I HAVE ALL THE ELECTRICAL CONNECTIONS RIGHT I DIDNT HAVE A DIAGRAM FOR THE VACCUM HOSES SO I INSTALLED THEM IN THE MOST LOGICAL AREAS. BUT IT IS THROWING A CODE FOR THE THROTTLE POS. SENSOR BUT SOUNDS LIKE A VACCUM PROBLEM. AND IT ALSO HAS A HIGH PITCH BUZZ AS THE RPM'S GET HIGHER AND WITHOUT MY FOOT ON THE ACCELERATOR THE CAR WILL DIE IMMEDIATLY DIE AND SOMETIMES IT WILL REV UP BY ITS SELF JUST BEFORE IT DIES. ANY IDEAS
