86FC RX-7

Ok i pulled off my throttle body the other day well i couldnt get it off because a house was stuck on it and i didnt want to cut it and buy a new one so i just put it back on and bolted everything back up. Now im having a vac leak andit sucks. If i hold the throttle it will keep it running but when i let go it will go to like 1000 stumble and die. Any ideas what might be wrong? ive check re-check and re-check again all the wires. I even took it off again and re put it on to make sure i put everything on.
