Default 82 crossfire rough idle

Car sat since last November . Change spark plugs (old ones were
very fouled.) Fresh tank of gas, new alternator, new battery, Hypertech
Streetrunner chip. Car still won't idle well at all. When started cold, it
backfires thru the TB (Primary) when you give it throttle. I created a
vacuum leak and the idle got higher,created a second vacuum leak and
the idle got even higher. Help !

Thanx

On the front of each TBI is a idle control motor, remove, clean and reinstall should help !
